I've just joined the site as I'm currently going crazy during this 2ww. I'm currently on day 4 post et where they transferred 2 good(so they said!) embryos (6 cell & 8 cell). This is my 4th cycle, 3 fresh and 1 frozen which didn't work. I have a little boy who has just turned 2 from the 2nd fresh cycle. He was a blastocyst when transferred however this time I had to have a 3 day transfer due to lack of good quality embryos. They had been using a camera system to watch development and said they're development was abnormal. These 2 seemingly were the best. Anyway, I'm having cramping and heavy legs in and off today feeling like my period is just around the corner. Surely it's too soon??? Can anyone shed any light on this? I cannot remember how I felt the time it worked.
