I am 7 days post embryo transfer ... I have only had symptoms that feel like twinges in my abdominal area, heartburn , and just today a headache. I have had no tenderness in my breast, no nausea , no spotting and I am fearful that my IVF with ICSI did not take. I had 6 fertilized embryos transfered - I did not have any illnesses or symptoms with my 2 other pregnancies, however, they were natural.
