I have been on the pill (Microgynon 30) for 18 days. My doctor said I was safe after 7 days. But other places have said it should be a whole cycle before I'm safe? Should I just listen to my doctor? I had sex 3 times that night without a condom, my boyfriend pulled out before ejaculating each time, but on the third occasion he ejaculated on my vagina. Since being on the pill I have vomited once, 9 hours after taking my pill. Am I at high risk of being pregnant? Or should I be fine?
