I have PCOS I’ve been off my birth control for 6 months. An I got a normal period in August an September came an I didn’t get it I’ve am 17-18 days late I have these pains in my lower stomach kinda like cramps but not as intense I do feel nauseous more than normal through out the day. I’m very tired could just be stress but it’s weird. My stomach feels bloated an tight. For the last two days my back has been killing me. An about 2-3 days ago I had to pee so much like every hour in a half or so. An ideas what this could be.
