Ok so I am 20 years old and I'm freaking out. I've been in a long distance relationship for a few years now but I'm still a Virgin. I had to visit my boyfriend a week ago because he recently lost his mother and we almost got intimate at some point during the time I was visiting him. I'm not ready to have sex yet so even though we were getting in the moment we didn't go any further. My period is 3 days late then I saw a little bit of blood and thought to myself ok good I have nothing to worry about but after I used the bathroom before bed I noticed I didn't have any blood. I can't be pregnant because I was definitely careful and we didn't go any further so it's impossible.My boyfriend never came in me so what's wrong with my period?
