I am in the 2ww after a fresh embryo transfer and I am due for a pregnancy test (bloods) in 6 days. Last night I forgot to take my dose of progesterone and I'm now worried I've really lessened my chances of success. I spoke to a nurse at Fertility Associates and she said it wasn't ideal which made me feel terrible. I was just wondering if anyone has had any experience of this or has any knowledge of how long your levels of progesterone stay high during the treatment. I took yesterday's dose at about 2:30pm and then took the next dose just before 6am this morning.
