Getting really nervous. I am now 5 days late. Having some cramping every now and then. I haven't had sex in 3 months (not sure if he used the condom correctly but he didn't finish and I took plan B) and I've receive both periods since then. They were somewhat shorter and lighter but still fairly heavy. I took a pregnancy test 3 days ago and it was negative. I haven't started really stressing until now. Could I still be pregnant? I'm starting to get pretty scared.
