IVF is a complex procedure, and most people don’t achieve success on their first try. Sometimes, couples need to go through at least three to four cycles to succeed in IVF treatment.

Usually, when an IVF cycle fails, women will bleed and get their period. They can resume their next cycle after their body recovers from the physical and emotional strain from the previous cycle. 

The most common question women have after a failed cycle is when they will get their period. This is a common worry because a delayed period after a failed cycle can cause adverse effects. 

In this article, we will discuss when women can expect to get their period after a failed IVF cycle and what measures they can take if it is delayed or irregular.

When to Expect Your First Period After Failed Implantation?

The time interval between a failed cycle and the first period depends on the woman’s body condition and hormonal levels. Some women will get their period three to five days after stopping the progesterone medication.

For some women, due to the high levels of progesterone in their bodies, they will have their period about one to two weeks after embryo transfer.

Late Period after Failed IVF Could I be Pregnant

While a late period after a failed IVF cycle can stir hopes of pregnancy, it’s crucial to understand the possibilities and proceed with realistic expectations.

Natural Conception

In rare cases, couples may conceive naturally after an IVF cycle before the next period starts. This could happen if you have unprotected intercourse and ovulate unexpectedly.

Residual HCG Levels

The hormone HCG (human chorionic gonadotropin) is used in IVF treatments to trigger ovulation and may also be part of the support protocol after embryo transfer. A late period and positive pregnancy test could sometimes be due to residual HCG from these medications, rather than a new pregnancy.

Factors that Affect When Period Will Return After Failed IVF or IUI

There are several factors that affect when periods start after a failed IUI or IVF cycle.

The main factor contributing to the delayed period is the progesterone increase in the body due to fertility medication. Progesterone is an indicator of pregnancy. So, it may take a while for the body to realize the failed implantation and expel the dead embryo.

Another factor that can affect periods is the woman’s age. As a woman ages and reaches menopause, her periods become irregular. This can also affect when the period starts after a failed cycle.

Other factors that can contribute to delayed periods are stress, health conditions, and lifestyle factors like smoking, diet, etc.

It’s important to consult with a best fertility specialist to understand how these factors might be impacting your individual cycle and what steps you can take to improve your health for future attempts. Women need to be healthy and in optimal condition during their IVF or IUI cycle.

Coping with Delayed Menstruation After Fertility Treatments

Many women may struggle with delayed periods after fertility treatments. They may worry that it may cause serious issues to their body. They can take some measures to cope with the emotional stress during this time.

Coping mechanisms include:

  • Keeping in touch with your healthcare professional and discussing what they can do,
  • Self-care methods, and
  • Requesting assistance from close ones.

You can also keep track of any changes in your menstrual cycle and use that information to determine how your body is responding to medication.

Irregular Periods after IVF Failure

Dealing with irregular periods after an IVF (In Vitro Fertilization) failure can be a distressing and confusing experience. It’s essential to understand that fluctuations in your menstrual cycle can be a common side effect due to the hormonal changes and emotional stress associated with the IVF process. Here’s a comprehensive look at the reasons behind irregular periods post-IVF failure and some steps you can take to manage and address these changes.

Understanding Irregular Periods After IVF Failure

Hormonal Fluctuations

IVF treatments involve the use of medications to stimulate the ovaries, leading to increased levels of hormones like estrogen and progesterone. After a cycle, especially if it doesn’t result in pregnancy, it can take some time for your body to readjust, leading to irregular or missed periods.

Emotional Stress

The emotional toll of undergoing IVF and experiencing a failure can’t be underestimated. Stress can have a significant impact on your menstrual cycle, potentially leading to irregularities.

Physical Stress

The procedures involved in IVF, such as egg retrieval and embryo transfer, are invasive and can put physical stress on your body, which might disrupt your regular cycle.

Seeking Medical Attention for Irregular Periods After Failed IUI or IVF

An irregular period is common after a failed IVF cycle. Though not all women have this condition, it is important to visit a best fertility doctor if your period becomes irregular.

Your healthcare professional can assess whether there are any underlying conditions that cause irregular periods and advise on what to do next.

They can also assist you in creating a strategy that will maximize your chances of success in subsequent treatment cycles. Keeping track of your menstrual cycle and having regular checkups will help you stay informed and take preventative measures to address any potential problems.

When to Try Again After Failed IVF Cycle?

The IVF treatment plan varies for each woman based on their health conditions and other factors. But, just to be on the safe side, doctors recommend women take at least a 4-week break between the end and the start of the next cycle.

That is, women must go through at least one full menstrual cycle before starting the next IVF cycle.


The time you will take to get your period after a failed IVF cycle will solely depend on your body and health conditions. Most women only succeed in IVF during their third or fourth cycles. So you don’t have to stress too much about it.

Follow what your fertility doctor says and take the medication they suggest without fail. You can improve your chances of getting pregnant significantly by following a healthy lifestyle and maintaining a healthy body.

Frequently asked questions

A woman who has had a failed IVF cycle may still have a late period and become pregnant. This may occur due to hormonal imbalances in the body.

It is best to take a pregnancy test or consult a fertility doctor to understand the reason for the delayed period or any complications related to possible pregnancy.

In most cases, your period should begin within one or two weeks after failed IVF. If your menstruation is delayed for longer than that, it is best to consult your fertility specialist to avoid any potential issues.

Menstruation can be delayed due to hormonal imbalances, which is a typical occurrence following IVF failure. In certain situations, the fertilized egg may not implant or develop after implantation, resulting in a chemical pregnancy and a delay in menstruation.
