I had unprotected sex with my bf which he came inside me last Jan 22 at 10: 30pm. Took 4 nordette as ecp jan 23 @ 4: 30am (6hrs after the deed) as first dose. I vomited at 8am in the morning (i think the pills were already ingested amd absorbed in my body already since its almost 4hrs since I vomited. Took the 2nd dose at 4: 30pm and another 4pills jan 24 at 2pm. Total of 12 pills. Iv been sick and nauseous and dizzy and tried no to vomit. My last period was Dec 27. I am normally late by a weeks sometimes. Im scared. Will the ecp works? Please guide.
