My girlfriend and I had sex 3 days ago. She was on birth control Tri-Sprintec for 2 months and never missed a day. Her and I had unprotected and I came inside her. We went to the drug store within an hour, bought Plan B. Her period was suppose to start the day after, which it did. But apparently it has stopped today. Can the Plan B be the reason its so weird? Any chance of pregnancy?
That close to her period is the safest time in her cycle to have unprotected sex. Unless she skipped pills, never take Plan B.
When she takes her pill as directed, every day is a safe day, evern during her period. When she is not on the pill, her fertile time is somewhere between her periods. So even then, the few days before her period are very safe.
