My period had ended on the 1st of July and I had unprotected sex on the 2nd. No ejaculation but I took plan b one step within 36 hours of intercourse. There was withdrawal bleeding after a week. On the 22nd of July I had unprotected sex and he came inside me. I took postinor 2 within 6-8 hours of intercourse and according to the pharmacist the second tablet is supposed to be taken 10 hours later which I did. It's been a week since my period is due, on the 28th of July. It hasn't come yet. Around a week late. Not sure if I should get a pregnancy test done or if Its just due to the pills. Having nausea and diarrhea and stomach cramps.
