thank you for your query.
If you have had sexual intercourse around the time of ovulation, chances of pregnancy
are definitely there, specially since the laparoscopy
proved that the tubes are patent.
As you are overdue by 7 days, please take a home urine pregnancy test to confirm your pregnancy.
Whether positive or negative, consult your gynecologist, for further treatment.
remain sexually active, and take regular folic acid
All the best.
