I am 34 y/o with no kids. I have never used the pill or any other birth control other than condoms. This month and for the first time, we decided to have unprotected sex to have a baby. My last period was Dec 27th, 2008 and we started having sex from Jan5th to the 15th every day. I was so sure I was pregnant. I just got my period today. I don't understand. Any suggestions? Do I have a problem? I am very regular and my cycles are 30-32 days on average
