Good afternoon, On April 29 I took emergency contraception after unprotected sex, and started bleeding 6 days later along with cramping. Assuming my period had started on a Sunday I started my birth control (trinessa) and continued taking pills as directed. I had unprotected sex again on my 4th pill day, and Oddly enough, im afraid my bleeding was mistaken for spotting as the EC side effects stated. Should I take another plan b pill or am I ok to continue my birth control pills?
