Hi guys, I recently just had a baby not to long ago she just turned 3 months old.. I also have a 22 month old daughter.. I've been on the depo shot for about 2 in a half months now.. Me and my boyfriend have unprotected sex about ever 2 to 3 days.. He sperms inside me everytime.. I know I know stupid me.. But I thought the birth control worked ok.. Now I have a sudden cold cough.. I'm having cramps, gas pains and my stomach is bloated.. My lower back is hurting and I have the sudden urge to throw up... I've thrown up a couple times and my gag reflexes are more intense.. My moods swings are worse then ever.. I just got off my period about a week ago but it wasn't heavy at all.. My periods are irregular and mostly last up to about 2 weeks.. Could I be pregnant?
