This is my first month using Wondfo pregnancy tests. I like that they're so cheap and I can take a bunch of them if I feel the need, but I'm finding that several have had "dye runs." I've recently had some pregnancy symptoms (nausea, sore nipples, fatigue, dizziness, etc.) but have only gotten negative tests using Wondfo - I'm currently on cycle day 57 and got a positive OPK on day 20. Irregular periods aren't unusual for me because I have PCOS, but the symptoms are something new. I guess my question is: has anyone gotten false negatives with Wondfo pregnancy tests amd have had better luck with another brand? Or should I just count myself out?
