Hello,
I assume you mean June and not July. That said, and assuming you have a
regularRegular insulin cycle, if you menstruated June 22, 2007, you could have become pregnant from
intercourseCauses of painful intercourse
Sexual intercourse - painful had ~8 days later. In a 28 day cycle, if day one is the start of menstruation, a
womanWomen's way would ovulate (ovary produce an egg) around day 14. Therefore, intercourse had around the time of ovulation has a good chance of resulting in a pregnancy.
Without assessing for the hormone of pregnancy, it will remain uncertain whether you were in fact bleeding from a miscarriage or an unusually heavy menses.
The one time administration of Novacaine should not have had any notable impact on the possible pregnancy.
Best regards,
Dr. Downing
