Pregnancy tests and PCOS

I was diagnosed with PCOS nearly ten years ago and have been trying to get pregnant about six months with treatments. . Since I started on the treatment my periods while not regular have come each month.. except for march.. I have been feeling slightly off.. simple things like going off foods I usually love nd having a lot more headaches etc... I want to test but I have read alot about hpt not being reliable nd getting false positives so I am a tad hesitant to make a move ... I am just lol looking for advice from people ..
