Hi guys so I've been with my boyfriend for a year now and we've been having sex all the time. However in June I felt that my body was off and I took a test and it came out positive. I waited a few more days and took another one and it was negative. My period was three days late but it was lighter than normal. I get my period still but now they're lighter than normal and I don't get really bad cramps anymore. I still feel like I could be pregnant due to I'm tired all the time and am always hungry. Not to mention I've been gaining weight and my stomach is getting rounder. Am I overreacting or should I go to the doctors?
