I received my depo shot before I got my period and I haven't gotten it yet, but I'm getting horrible cramps and feeling like I may puke before I go to sleep every night. But I just am wondering if it would be normal for me to just not get my period since I get the depo shot before my period started or if I may be pregnant? (Because there is also a slight possibility I may be pregnant but didn't realize until after I got my depo shot... but my partner did not ejaculate at all.) So if someone could help that'd be great!!!
