I am 30 weeks and three days pregnant. My last period was the 15th of September 2008. I was with my ex up to the 2nd of October. We were together for 5 years on and off and I was never on any thing to stop me getting pregnant. I was with another man on the 26th of September 2008. Can you tell me when was the time that I conceived please help

With just a one week difference it is too close to call. Were you protected or unprotected with the other man on the 26th?. protected would make it less likely to be his. Did you have sex with your ex between the last period and time with other man?

Either way, the only way you are going to know is to have both go along with some testing after baby is born.

Hope it turns out how you would like it to.
