Hello today is day 58 since the first day of my last period and I've never missed a period or had a cycle longer than 37 days. Although not as often as weeks before I still have nauseous and I'll be really really hungry make something to eat and not want it rather not eat. My weight keeps fluctuating. I've had occasional cramps but not like my period ones and I've been super overemotional almost bipolar. My veins have been poppi for the last week. I've had a rash similar to hives. Umm I was on bc but literally lost it the day I started my period on July 17 and havnt been on it until the last 4 days...I've tried taking the ones that make you start...and still nothing. I've been constipated. My boobs feel like firmer or fuller and my innie nipple has been out a lot and ttheyre sensitive as hell & I've never had sensitive boobs. It feels weird to lay on tummy kinda feels like I drank water too fast. I'd be 8 weeks pregnant if I am. Are any of these symptoms signs that I could be? I've had 2 negative blood tests now. I really really wish I could just get an ultrasound just to see if there's a darn baby in there. I'm also a cigerette smoker and smoke weed and would stop these things if I knew. Idk. I'm 18. I'm scared.
