Hi Ladies, on 26/04/2014 I had a 5 day embryo transfer. This is my second transfer (the first resulted in a pregnancy). With my first pregnancy, I had no symptoms or side effects at all. This time, I have had a meaty taste in mouth, twinges in my abdomen, some chest pains, and of course a delayed period. I had a blood test yesterday (12 days after ET) and it was negative. Has anyone else experienced side effects from the process? Can progesterone give you these side effects? Thanks
