I know that this is no substitute for a test, but I need to ask anyway.

My cycles are usually 34-37 days long. My last period began on Dec. 2 and on Dec. 26 I had sex around 2 a.m. After the plane ride home I took Plan B (approximately 14 hours after the incident). We did not use condoms, but he did not ejaculate in me. I know that this wasn't smart, but I am worried. I'm not sure when I ovulate so I am not sure if this took place during my fertile period. I have not received my period since then.
