I had my IVF transfer on March 17th. I transfered 3 embryo's which all made it to the day 5 blastocyst stage. Since then around 6dpt I have had mild cramping off and on and just weird back pains. The back pains even make my side hurt at times. I have my beta test tomorrow and I just hope that I finally get the positive. This 2ww is very hard because you don't know if it is the medicines or your body accepting the change. Any thoughts on these symptoms would be appreciated.
