So sick of false positives

Katt

Been trying to conceive for two years. I ovulate by tracking and ov test. So month after month I’m tracking. Bare in mind my periods are irregular so it’s hard to continuously track. Not alone expensive with the tests. I got pregnant but there’s wasn’t anything in there. I track and I have tests. I have some positive. But turns out that tests are faulty or I’m constantly getting chemicals. I don’t know when I’m due on. Constant got a pad ready. Periods are like brown the a day of red then brown. Here there and everywhere. I’m 41 next month so I know they be irregular at some point. I’ve had hormones checked etc all ‘normal’ so I’m literally at a loss now. Don’t know what else to try to get them levelled out. Any help.
