Hi. On Wednesday my boyfriend fingered me, and it is possible that he had precum on his finger... I am taking diane 35 as well, and i am almost sure that i had taken all the pills in the last 7 days before this happened.. But on Saturday, 3 days after my boyfriend had fingered me, I started taking antibiotics, though there always were 4 hours between taking the antibiotic and the diane 35. I am really afraid, because I had been pregnant once before... PLZ HELP as soons as possible.
