Assuming you live in a country where abortion is safe and legal then yes, you can abort a pregnancy at 11 weeks. If you live somewhere where abortion is illegal then I'm really not sure because I think you would need surgery to abort at that stage.

To get the age of pregnancy you start counting the weeks from the first day of the woman's last period. Roughly speaking, by the time a woman misses her next period she is considered 4 weeks pregnant, even though it's likely only been 2 weeks since conception occurred.

Good luck!
