July 15 my girlfriend and I had sex the day she stopped bleeding. She ended up taking plan b and got another perioder a few days later. Then on August 4 she got the depo shot for the first time and but we didn't know we were supposed to wait a month for it to start working. We had sex on August 15 and the condom broke now 3 to 4 days later she feels a little neaseous sometimes. Could she be pregnant? I have the plan b pill but I don't know if it would hurt her to take it. Please help. I need an actual answer not something that you copied and pasted from the depo shot website
