I missed 2 days of my birth control 4 days ago. Spotting occurred but I did what the instructions told me to and doubled up for one day and took one pill daily since. I had unprotected last night (4 days after missed pill but 5 pills have been in system) and he did not come inside of me but I am worried about precum. I just want to know the CHANCES of me being pregnant. Should I take EC?
