My girlfriend and I had sex on the 10 of this month I used a condom and came outside but I'm not sure if the condom broke or not, her dates were due on 19th she'd pretty irregular dates in the past but for sometime they have been on the se date every month, now she's late 7 days and don't have any of the symptoms just had a nausea like feeling once a few days back, is she
pregnant?
