Sara, the spotting after EPU is completely normal. I won't go into why in case you are blissfully ignorant of what actually happens during the procedure and would prefer to remain that way - I know I wished I could have when I found out (sadly before my first one!). As for the constipation - perfectly normal with pregnyl in your system, and completely normal during pregnancy as well. Your ovaries are likely feeling a little swollen because of what they do during EPU - they won't just be attacking the follicles that are likely to have eggs, I believe they go for all of them, even if they are under-sized, so they have been through quite a bit! And you can probably begin to understand a little of why I spent a week in hospital after having 32 eggs collected! Don't be jealous of the egg numbers - they were all crap! Hang in there... Hoping your embryos go well in the next few days and you get to ET this cycle.
