I was told I have a cyst inside 1 of my ovaries about 6 months ago after having an ultrasound. I've read that cysts can cause a false positive pregnancy test and I have a few of them that are faintly positive but I don't yet know for sure if i am pregnant or if its just a false result. My period is 2 days away by my calculation. The problem is I'm not seeing a positive on every test I do.
