As a 19 year old girl, this is probably the most confusing and scary situation i could imagine to be in at my age. I am a month late on my period and i have taken 2 home tests that came out negative and one at the school nurses that came out negative. The latest ive ever been before was a week, and that was when i was around 16. I dont think its the stress, because i have been a lot more stressed before than i have been lately and still gotten it. A little over a month ago, me and my boyfriend had sex and he went inside me. 2 days later i took plan B. I dont know if maybe it worked or not? And even since then me and my boyfriend just go by the pull out method. I know i shouldent but with the bad self esteem and everything, i thought i would never get pregnant. I have been trying to ignore this whole situation, and thinkin eh whatever and not stressing it because i know stress would prolong. But today i hinted to my mom i was late, and she didnt seem very happy. So now, im thinkin oh no, what could be goin on? As far as symptoms, I have been a little crampy now and then, but it never stays and i dont get my period. My back has been aching none stop, ive been peeing more freguently than normal, i feel yucky every morning but never peuke, my nipples are a little sensitive, but not too painful or anything, Im tired and exhausted almost 80% of the day, even when i go to bed early, and thats it for now. Im thinking that maybe all that can be something else? And What else should i be looking for? And i dont quiet want to go to the doctors yet, my medicaid just ran out and i dont want to go for nothing. And plus ive heard of people taking tests and getting negative even when two months later they find out they really were pregnant. Can someone please help me out?
