Hello, and I hope I can help you today.
Is extremely unusual for women to conceive without having intercourse because semen dies when exposed to air. However, if there were any drops a semen that were directly connected by liquid to your vaginal fluid, there is a possibility that the sperm could swim into your vagina theoretically putting you at risk for
pregnancy.
In addition, it is unusual for women to ovulate before day seven of their menstrual cycle. Most women ovulate about two weeks before their period starts, so counting backwards, you probably ovulate around the 10th to the 12th of the month, so you did not have sex during a time where ovulation typically takes place.
So in summary, you are theoretical risk for pregnancy, however the actual likelihood giving your situation is extremely low. I would not worry about conceiving in the situation, however if your menstrual cycle is late this month, I would confirm with an over-the-counter urine pregnancy test to make sure your results are negative.
I hope I was able to adequately answer your question today, and that this information was helpful.
Best wishes,
Dr. Brown
