I have been on the Depo shot for a year and I was supposed to get my next injection on April 7,2010 but I missed it. I was two weeks late for my injection on April 23, when I went to the doctor. Before they gave me the shot they did a urine test to see if I was pregnant, it was negative. My fiance and I had unprotected sex on April 19 and April 22, could I still be pregnant since we had sex twice in the same week I received the depo shot? And if I am can it harm the baby since I have received the depo injection already? Please help!
