I Had Frozen Embryo Transfer ETPP IVF (natural Cycle IVF).

I had frozen embryo transfer ETPP IVF (natural Cycle IVF). I am suffering from constipation. My bowel stored in carve of my backside and it is very difficult to tolerate this. Besides all related medicines I am having duphalac. But with no result. This problem was prior to embryo transfer, actually since my childhood.
