Hi. I currently suffer from PCOS and have been on metformin for the past six months to treat. My periods are still a little irregular, but I was supposed to start my period on December 5th. According to my app and egg white discharge, I supposedly and hopefully ovulated November 19-24. My husband and I are very sexually active and are trying to conceive so we haven't been using birth control. Well I missed my projected period and have been having TONS of cramps, along with breast tenderness, fatigue, bloated ness, all the things that are typical pms, except for the past three days. I've started to become very nauseous, queasy, lots of reflux and burping, along with loose bowels. Then today, I started spotting brown discharge and having major dizzy spells. I've taken more pregnancy tests than I care to admit, but they're all negative. Coukd I still be pregnant? Is this just my period and crazy symptoms? Is my PCOS playing a cruel joke? Have any of you experienced this?
