Implantation cramps vs progesterone cramps?!

Lauren

Had my FET on 2/21. Woke up today with slight cramping of some sort that has been going on all morning. Feels different from my usual period cramps, but can be cramping due to the transfer, implementation or progesterone. Already driving myself crazy! Beta 3/1.

What symptoms, if any, did you have before getting a positive from your Beta??
