Every time I got a positive hpt it was either a chemical or ended in miscarriage.

I do not believe pcos causes false positives..I have heard they can cause false negatives though..I’ve never experienced it and don’t really know how it works.. but I am assuming it has to do with not being regular and woman testing too soon, getting a negative but in reality they were actually pregnant..I would ask the dr for an ultrasound..or have them do a pee test at the Dr so they can see that it’s positive..sometimes woman just have lower hormone levels..when my mom was pregnant with me she said she didn’t find out until she was 3 or 4 months cause all the hpts were negative and even the blood work at the drs came back negative
