OK so I am due on July 13, 2009 according to my last period. It says I got pregnant in the middle of oct. I seen my ex on or around September 20th is there anyway I could have gotten pregnant in September? He said he "pulled out". I had my last period on 0ct. 5, 2008. Can I be pregnant from what happened in September?

Yep, definitely, ''pulling out'' is not an effective method of birth control, 'pre-' that escapes during sex could get you pregnant for sure.

If you have had a scan and dates have not changed much, your measurements are not off by much, your period in October was "normal" as in when it arrived, amount, and how long it lasted, odds are slim that it would be your ex's. While the withdrawl method is not the best form of birth control, if used correctly, it is certainly better than nothing.
