I'm at a loss

Hey everyone I'm at a total loss here. I got off birth control the day before my husband and I moved. I also had what I assumed was my period as I bled heavy for a few days then nothing unless I had sex and after we stopped and he pulled out there was brownish discharge for a few times then just normal discharge this was in May. It's July and I haven't had a period yet! I've taken many tests and they're all negative! Today I had thick clear discharge that had a little blood so I assumed I was getting my period but I never had anything else after. What the hell is going on?! Also sorry for the TMI.
