How many months do you have to wait to do a frozen embryo transfer after taking two shots of methotrexate to treat an ectopic pregnacy? ?

Two months. Two, sometimes 2 & 1/2 months is needed to excrete the more active metabolites of mtx.
It takes 2 1/2 mo to. 14 weeks are necessary to get rid of mtx-polyglumates which are 70x more potent than mtx. There is no effect on ovulation.
Waiting... Your doctor will be able to tell you after the ectopic pregnancy resolves and he has the blood tests and ultrasound images to proceed with confidence. Good luck !

Wait for both. What is the status of the ectopic? Is it gone? You ob-gyn can advise you for this indication. The half life of Methotrexate can help clarify when it is out of your system. It is up to 15 hours and we usually suggest 5 1/2 lives to get a drug out of your system but this is affected by the indication for therapy and its mechanism of action. Your ob-gyn can guide you in this answer. Read more...

My first transfer resulted in ectopic pregnancy. Is there anything I could do to avoid this from happening in my upcoming frozen embryo transfer?

Not really. If it's an in utero transfer, there's not much you can do to actually prevent an ectopic pregnancy. Obviously you are at risk of another ectopic pregnancy. However, your doctor will keep a close eye on you. Read more...
