I am scheduled for frozen embryo transfer of 5 day blastocyst on next Thursday; 18 th of February. The clinic informed me to start progesterone next Sunday. Accordingly, I will be taking progesterone for four days and I will transfer on the fifth. Is this the usual protocol? Do Ladies receive progesterone for four or five days before the day of transfer?

Any experience which is better; Crinone gel versus cyclogest pessaries?

Most people have an implantation window of around 5 days (120 hours) of progesterone (Im a bit of an oddity where I need 6 days, had an ERA test to check after lots of failures). With regards to the drugs, I personally would go for cyclogest as I don't have a good history with crinone. Best of luck.xx

Thank you for your replyCongratulations on your pregnancy. Hope your babies are doing well

So you mean you received five days of progesterone and you transferred on the sixth?

Sorry, I've miscalculated. I think your time on progesterone is a day short but they may have good reason for this so would question it.xx

I’m with Cinderella on this. I’m also an oddity at 6 days after an ERA but most people are 5 days. Would also agree that you might be a day short so would double check with the clinic x

Thank you Congratulations on your pregnancy

I checked with my clinic and they informed that their protocol is to give 4.5 days of progesterone, so full four days before of progesterone and morning dose on the day of transfer

I was prescribed vaginal pessaries 400 mg twice daily & progesterone injection every other day so a total of 4.5 days

Does this sound ok or shall I call them again ?

I’m sure it’s fine if this is what they have said. Every clinic is different in its approach so it’s so hard to say that one size fits all! If that’s their protocol then I’d go with it. Good luck xx

Congratulations on your pregnancy dearSo, did you four whole days of progesterone and and the morning day of transfer?

May I ask you too if. Your were you receiving vaginal pessaries only or together with injections?

Hi. I did both vaginal pessaries and injections. I can't remember now if I started just in the evening on the Thursday with the injection and the pessaries together, or started the pessaries in the morning or the night before. But your doctor should tell you!! Just letting you know I had a similar protocol :)
