Hello I am 22yrs old. I had sex with my BF on 5th Oct, Though there was no penetration but he rubbed his penis near my vagina and semen stuck on the outer layer of my vagina. I was confused so next morning, means on 6th I took an I-Pill. After that I had severe headache for two days. Next, I had bleeding on 17th till 21st with lower abdominal and back pain. Last month I got my period, 4 days late that's on 27th September, for some unknown reason, So according to my cycle I should have got my period Yesterday which I didn't got. Today means on 28th, I had a Urine
Pregnancy Test & it came negative. So should I consider myself safe from being
Pregnant ? Please clear my doubts as I don't want to be pregnant right now.
