Why Does It Take So Long for Periods to Start After Embryo Transfer?

Embryo transfer is the last and the most awaited step of the IVF treatment. Then there are a wait of 2 weeks (14-15) days. Then the pregnancy test is taken. If the process was unsuccessful, the capillaries in the wall of the uterus get ruptured and the embryo is no more able to implant itself and thus periods occur.

Had the embryo been transplanted correctly, the patient would have been pregnant. Light bleeding occurs when the embryo implants itself and small capillaries of the wall get ruptured. A period clearly indicates that the embryo transfer and the wait to become a mother had been unsuccessful for the time being.

There are certain steps that you should follow if you had an embryo transfer. The very first one being- complete bed rest. The doctors would also advise the same for the upcoming 2 weeks. Also, avoid any sort of strenuous works.

Drinking plenty of fluids is a must so that the cells stay hydrated. Avoid alcohol and say yes to a healthy diet. Avoid going out in extreme temperatures as this might increase the chances of infections.


What you eat plays a major role in your body system so it should be done with utmost care. Healthy food will definitely respond better to embryo transfer. You should include in your diet, foods that are rich in zinc, folic acid, fats, carbohydrates.

Eating avocado would be of help as it has a lot of fats and has vitamins and minerals that support overall reproductive health. And above all, water is a must to cure many.


Periods occur after 12-16 days of embryo transfer. It is a clear indication of the negative result of the procedure, i.e., the pregnancy did not happen.

The time duration is this long because the embryo takes this long to implant itself. If not, the capillaries along the wall of the uterus get ruptured, and thus period occurs.

In such a case, you need not be depressed or sad. Losing hope is not the thing. If the process failed, give it another try.
