idk iif im just paranoid or what. but in the past month or so ive gained a good chunk of weight. all but one pair of jeans fit, and they were my "fat jeans" normally i would be about a size 7/9 but now im almost a 13. nothing in my diet or exersice has changed really, i havent been eating as much fast food or pop this summer tho. so youd think if anything i would loose weight. i have been feeling like i have to puke but i havent. my nipples were sore, but not as much now. my period has stayed the same, but its always been odd. i used to be animc and i think i may be agian. im way tired and sore all the time now. and for the past few days i feel my tummy moving weird, but maybe its just gas, but it doesnt feel how gas normally feels like. i took a pregnancy test a few months ago and it was negative, there was a verry faint extra line tho...[one line was neg. 2 lines were pos.] hardly visible to the human eye. i do have sex about every day, a few times a day, so i know it is possible to be pregnant, i dont think i am, but all these things are messing with me. whats going on?? do you think i am or no? coule it be something else?
