I and my gf had sex on her 5th day of menstrual cycle. I ejaculated inside and as a precuation after that she took an i-pill within 2 hours of it which she vomited after 3 hours of intake. As another precautionary step, she again took an i-pill after 40 hours and this time all went well. Then she observed bleeding after 5 days of the i-pill. Now, after all that episode, her periods are 10 days late from the start of the first menstrual cycle if counted in that order. Please suggest what do we do next. Also, around a week back she had lot of brownish discharge and white discharge after that followed by stomachache and cramps but no periods.
