Got a positive test Monday night, nausea, sore boob, boobs with bright blue veins, smells intensified, crying all the time etc. got a light positive Tuesday morning and negatives since. Now when I wiped there was a bit of pink called dr going in tomorrow for ultrasound and bloodwork. Now when I wipe it’s brown. Just took a digital and said not pregnant, I think I’m miscarrying. Anyone have any advice?
