When did I get pregnant?

[bubbles09]

If my period started on Dec. 10 and I had sex on Dec. 17 could I have gotten pregnant from that time. Or was it after that.

HI!
It would be unlikely for someone to get pregnant on cycle day 7. Many people are still bleeding on that day.  More likely to be a later day such as day 12-14.  HOWEVER anything is possible when it comes to pregnancy.  If you have an early ultrasound that gives you a due date, you can calculate the date of conception backwards from that.  This should be accurate within 3-4 days.
Hope this helps!

according to the Ovulation Calculator the best time for you to get pregnant would ve dec21 to the 26 which means most likely it could be that date cuz sperm can last up to three days or more. So either date is possible.

No, because it is November. Did you mean November?

How long is your cycle? You can use an ovulation calculator to figure this out, but even if you did get pregnant it is probably way too soon to tell.
