on december 22, 2010 my bf and i had sex for the first time(it was also the last day of my period). we used a condom, but the condom he used was a keychaiin. which isnt very safe. he says it didn't break, but it was a keychain. after that, i missed my period in january, i then took a test. it said negative, but it was a cheep one, and i didnt follow directions completely. i got my period in february but not one in march. i also got a period in april. and it is now march, and im waiting for my next period. my bf and i also had oral sex. he rubbed his penis on my vagina(without clothes) and he went on my vagina. all ive been wanting to do anymore is eat, and ive gained weight. i play a sport and tried working out, but i still have a stomach. it almost looks like a babybump. but if i was pregnant it would be five months, is that too early to show? also, i have pain in my lower abdomen. it is like a cramp, but its different thn my normal cramping. should i get a different test?
