I am 15 yrs old and almost a month ago me and my boyfriend had unprotected sex, after the time of my period, now I have missed this month's period which was supposed to be here on the 15th of march it is now the 17th of march, and im a bit concerned, ive been researching some symptoms of pregnancy and I have not been getting sick or anything to that matter, I feel fine. I also read that stress can be the result of a missed period, well I dont know if u would call this stress but I have been worried about being pregnant, and I think about it constantly, do u think I am just stressing myself out and that is why I have missed my period, or do u think I could be pregnant?! And if u think I could be pregnant should I go take a pregnancy test right away?! And another thing I have read on other information sites about pregnancy and missed periods and I have learned that in the teenage years it is sometimes common for you to miss a period or for it to come late...Im really concerned someone reply asap!! Thnx!!! :?
