I got a positive pregnancy test june 1st (same day my period was supposed to start) i had sex 6 days before, is it possible i got pregnant that day (may 26th) ??

Not likely at all: It is very unlikely that 6 days after genito-sexual vaginal intercourse with a fertile man that your urine pregnancy test or that your blood betaHCG pregnancy test would be positive.If the June 1st pregnancy test is a true positive, you probably got pregnant earlier than May 26th.Check you blood betaHCG levels and seek a pelvic sonogram (dating scan) once your levels are above 1,000 mIU/ml
