I've had protected sex with condoms not even a week ago. I'm planning on getting the Depo shot this Friday, the 18th of March, and I'm a bit of worry wort. I was wondering, with the slight chance of me being pregnant, if I got the shot not even a week after "conception". Would it spontaneously abort? Would it hurt me? Would it keep the baby but give it birth defects? I'm not really sure and I would like my question answered because I am very worried. We used the condoms properly, no breaks or slippage. So, I highly doubt I am pregnant. My period should be due tomorrow or Friday (the day I get the shot). But I'm worried that my period won't come by Friday to prove to me that I am not pregnant. Does having sex for the first time throw off your menstrual cycle, maybe?
Please answer ASAP! Thanks!
