My body is confused -__-

My periods have been regular since I quit taking my birth control in January. We have been TTC since then. Last month my period was 10 days early with no period symptoms and nothing but small clots. I've taken multiple tests and all negative. My expected period is 2 days late now and my doctor put me on provera to regulate my cycle. I feel like my body is now confused because of this and I'm so frustrated. I want another baby :(

Has anyone one had a similar situation?
