Hello, three months ago i thought i was pregnant, my period ended up late but i got it, then the second month i got it again but I read online you can still get your period and be pregnant. Finally, there's a dark line from my belly button to my pelvic area and i read that means you're pregnant. Please, i've never even had sex before and all I did was dry hump with my boyfriend with four layers of clothing on. i'm absolutely terrified of this dark line, because there's not other explanation. Help me please.
