7mo pp haven't gotten a period yet just spotted twice this month only in the am weird discription but I feel like my uterus as I call it lady bits are sore and crampy it was so bad earlier I was going to drive back as home from being on my way to school I tool a test it was negative took out the trash and I'm assuming it was and evap line cause it was almost not visible I had to squint, I'd why I'm spotting twice this month just tried to eat shrimp got nauseous and had to go to the bathroom thinking I was going to hurl but seriously I'm aching like I'm on a period but a bad one with no blood...I'm done wasting money on test if it's not that ,I hate when I call the docs they really won't see me unless I'm pregnant or want to talk about birthcontrol...should I try a primary doctor instead of a ob/gyn anybody have this
