I had sex a week ago and he used a condom and as far as I know it didn't break and there were no tears/leaks! it was the day my period ended! I was sick with fever for a few days and now I'm really worried I'm pregnant! I feel like I'm experiencing symptoms of pregnancy, my back is sore! Is it possible I'm imagining these symptoms just because I'm stressed? Can anyone help? Do you think I'm pregnant?
