Patient: Gf swallowed my sperms during a blowjob ..i didn’t went to her vaginal area in fear of her becoming pregnant …now 5-6 days after that she’s having an early period…i m nt sure whether its normal period or implantation bleeding..she’s having abdominal pain on right side …i m very tensed about this….can it be implantation bleeding because of sperms which she swallowed?…is it implantation bleeding?…. can she be pregnanet in any way?..i m thinking of suiciding because of this much tension which i m taking….can she be pregnant?
