Well, I have taken home test to check if I am pregnant, but all come out not pregnant. I took a birth control shot in Feb and I haven't had my period yet, yes I'm sexually active, but have used a condom at all times. My breast are sore, like growing pains, and nipples tinder, I bloat (plus lactose, sometimes bloating due to food), and suffer period pains. Am I pregnant? or over worrying when it could be growing pains?
