Unprotected sex on day3 of my period. No ejaculation. Had ec pills less than 24hrs after. Then another unprotected sex on day9 after my period. No ejaculation again. Had postinor 2 less than 48hrs after. Withdrawal bleeding 4days after. Negative tests so far on day16. But I get blood spotting and vaginal discharge a week after. And I've the full digestive feeling. Should I still be worried that I'm pregnant? Or is it just the side effect?
