Ovulation prior to a FET advice please💕

[Chinese13]

Hi all. I am having a medicated frozen transfer and I am not having my first scan and blood test abroad until day 17. I am worried I may have already ovulated by then and in which case will my cycle be cancelled or my transfer less likely to work?

I am thinking this because I thought transfer had to be 5 days after ovulation and I won’t have enough time then to have 5 days of progesterone prior to the transfer? I am not having a meds to prevent ovulation. Has anyone have cetrotide prior to a frozen transfer please? I am so stressed and worried about this now. Thank you x

if its a medicated cycle (where you take oestrogen tablets to prepare the lining) then don't worry as this will stop you from ovulating naturally. My doctor told me that the #days of oestrogen isn't that important. Its the progesterone timing that matters. So I've done transfers ranging from about 11-17 days of oestrogen before. The timing has differed due to work commitments and because of weekends etc when my clinic is closed. They usually check at my lining scan to make sure that my ovaries are quiet, and that my body has not prepared an egg for ovualtion on its own but its always been fine. If your not doing medicated and are doing a natural/modified natural cycle then you don't normally have any estrogen. You use OPKs to monitor your LH surge and then contact the clinic when this happens (ovulation will occur 24-48 hours later). Some clinics are more hands on and monitor bloods etc so its more precise or give a trigger shot to force ovulation when the follicle reaches a certain size
