My gf had her period on march 11-15. We did the deed on march 24 10am which was her fertile period according to the calendar app. I used a condom but after releasing my cum in the condom, I would pee and would not put on a condom for the next round but I release my cum outside. My gf also pees after our rounds. A day after the deed, I bought her nordette (white pills) and she took 4 pills on march 25 9am and and another 4 pills on 9pm for the 2nd dose. By 12 midnight she experienced nausea and she vomitted but the pill was not included. By 2 am she vomitted again and she said it was bitter. We are afraid that she vomitted the dissolved pill which would lessen the effectivity of the pill. Please help us.
