So the date of my last menstrual period was somewhere between August 5 and 10. I honestly don't remember when it started, it has always been irregular. Anyways, it only lasted a few days and then I had sex a couple of weeks after, and on September 4 and 8th. This is around when I was supposed to have started again right? The reason I'm concerned is that on the 4th, I had sex and we used the pull-out method, which I see now was a bad idea. It is now the 20th and I haven't had my period yet for this month. This isn't normal for me. I always get it every month, even if it's just a few days late. Now, it's almost 3 weeks late. I'm trying not to freak out right now, but it's getting harder every day I don't start. What are signs of pregnancy? This is all new for me. I don't know what to look out for. Right now, my abdomen is a little bloated (normal for before a period right?). I get an occasional cramp, but nothing like what I would get with PMS. Also, my breasts are a little sensitve (this does NOT happen ever before my period.) And I seem to be set off more lately by the smallest of annoyances. I also am a lot more touchy than normal (with PMS I mean) and I have started being more tired lately and therefore crying when I get frustrated and tired. As in, crying for absolutely no reason and feeling stupid afterwards for being so emotional. Can someone please explain all of this to me? I'm afraid to go see my doctor for a test. If I am pregnant, I would more than likely be all alone in this situation. And can someone help me figure out the timeline, based on my last period and when I had unprotected sex? Please any advice will help.
