Last month that's july my periods started on 8th and went off by 12 and on 27th I had unprotected sex where he didn't ejaculate inside. On 28th july I found it started bleeding which was like periods twice a month. There were cramping, heavy flow etc. That bleeding continued till 8th of august. Also when I was bleeding on 28th july, I had a pill of unwanted 72 and another dosage of the same pill on 29th july maintaining 12 hours in between two pills. Nowadays i'm urinating frequency. The left side of my vagina cramps at times. Slight cramps though. I feel paranoid with the thought of getting pregnant. Acidity is there. Are there any chances of getting pregnant? Please help me out with this.
