Hi. I have a question about IVF protocol (fresh shared egg donor); I m 1 of the recipients. I recently finished succesfull (3rd attempt) mock cycle using delestrogen injections, then was erroneously told by nurse to wait for natural period. After 16 days of finishing drug (in comparison, get AF 3 days after oral estrace), I called her to inquire why it was taking so long, to find out I should have take Provera 12 days prior! I hadn t a clue since neither I or my donor hadn t been prescribed anything during that time by my clinic. Hence, my questions are: 1-is there a small chance I m pregnant as I had intercourse shortly after ceasing delestrogen and if so, will Provera be detrimental? 2-If not, have I simply (with the help of my great nurse) held up the protocol for everyone else? Kindly advise B
