My husband and I had unprotected sex 4 days before my period was due. I'm three days late now, is there a possibility that I could be pregnant? Or rather how likely is it? I'm fairly certain that I ovulated late, but not sure. I also had some cramping Tuesday night that made me think I was going to start, but then nothing since. I know that if I take a test now it'll likely be negative. Feel free to tell me your stories and advice. Thanks ladies!
