I had sex for the first time about 3 weeks ago, he didn't use a condom but he pulled out and I never got any semen in me. We've done it a couple of times since then also I also took the emergency pill. I'm supposed to get my period sometime soon (I get it around the 27th/28th?) but it hasn't come yet. I have cramps as if I had my period, but there's just no blood sometimes a little light red like if it's mixed with water . I'm super stressed out about this. I can't tell my parents (personal reasons) a nd I can't go buy a preganancy test to find out. Could I possibly be pregnant? I'm so worried about this, and any advice would be appreciated.
