My last period started on 15 feb. had intercourse on 15th feb and again on 28th february. r my chances of pregnancy high? when is earliest time to tes

35 days after period: I usually tell my patients trying to conceive that they should take a pregnancy test 35 days after the first day of their last period (so this would be a week after your period should have started). Most pregnancy tests claim that they can be performed right at the time, or a few days beyond, a missed period. But, to avoid confusion, i tell my patients to wait a full week beyond.
