question: Hi, i am 33 years old. 6 days past 5 day blastocyst transfer. Transferred 2 embryos on 10/25 .. i felt sharp pains / twinges here and there for the 1st 2 days then felt totally normal, not even bloated. Now the past 2 days i have been bloated and cramp and now am pooping like crazy (TMI sorry!!) i did a home preg test this morning and it was negative.. i had to increase my estradiol from 2 tablets to 3 a day ... are these signs of a failed IVF cycle??
