This is weird to me

Chatee

I've downloaded 3 period tracking apps. 2 coincide with each other the other one is off by one day. Now I'm not sure when I ovulate but I can feel it when it happen, I believe. I've had unprotected sex resulting in 3 sessions & 2 resulting in coming in me in one day and on the app it's suppose to be my ovulation day. Which I don't believe it is. I've taken 2 pregnant tests and I've concluded I might be early if I am pregnant. Fwd I felt moist last night, I wiped and it was that brown discharge as if my period was coming. I put a pad on and went to sleep. I wake up nothing is on my pad. I feel like my period has came so I pee and wipe and it's that light brown discharge again. I'm at work and it looks like a strip of brown discharge. Not 1 red dot! I've been on shift changed my pad and ntn, I've gone to the bathroom and wiped ntn. I dont know could I be pregnant? I'm suppose to get my period yesterday/today. I'm going to wait till tm to test again. Hopefully I get a positive or the blood drops. Something have to give!
