Ok 2 1/2 months ago I had unprotected sex. I missed my first period so I was just gonna wait till next month to see if I got my next period. I got my first period on the 10th of july but then I had another period of bleeding on the 28th which lasted till the 1st and I still have all my periods but they aint regulated and on time and usually last only a day or two. But I also have all the symptoms of being pregnant. I'm always tired I have to pee every half hour. Always have headaches and smells seem so strong to me, I smoke and I cant stand to smoke nomore because of the smell and taste and ive been smoking for 4 years and no problems till now. My boobs are getting very big and are very sore. My belly is gettin a little bigger but I dont know if its eating or not.. And my lower back always hurts.. When I get stressed or walk alot my stomach starts to hurt. The weirdest thing of all is every once in a while I can feel something I dont know if its a baby or not moving around(in my lower region of my belly) all my friends have felt it and say im pregnant but I still have periods.. Could I really be pregnant and still have my period?? Last thing my best friend is pregnant and she lives with her boyfriend and she told me when she has sex it hurts because she can feel his penis moving the baby.. And it hurts everytime I have sex I can feel something weird but I dont know if im overreacting.. Someone please help me ive been going through hell wondering. I cant buy a test because where I live they are behind the counter and you have to be 18 to buy them and im not... Just someone please give me some answers or something...
