My period is 2 weeks late. My period is regular ever since. But I have an active sexual life. We use the pull out method and always make sure that no sperm esp. The first burst will be inside me. I'm not just sure if he excreted it in front of my vagina. I'm afraid it came in. In happened on February. I remember I got my period on Feb. 14, and lasted til Feb 19. I expected my period to come from March 20-26. I had sex on March 23. We made sure he didn't cum inside. Now my period won't come. It's almost 2 weeks late. I used pregnancy test several times. All negative. I think i'm using in right. I used pregnancy test strips, even pregnancy test cassetes. It's all negative. I'm always feeling dizzy last March but I think that's because I don't get enough sleep. I'm often stress out and not feeling well to. I feel something in my belly I can't describe. My vagina is sometimes dry, sometimes it releases white sticky substance. But results are always negative. Am I pregnant? Thank you so much!
