Help please!!!!

Ok so I’m on cd 44, I haven’t had a period but yesterday I bled some. Not enough to fill a pad or tampon. And it went away after an hour. I thought I had started my period but realized after it went away I didn’t. Well then today it did it AGAIN!! I’m so frustrated because I keep getting BFN and my period isn’t showing. I’m usually a 30 day cycle. I’ve never missed a period.
