Hello. Im 25 and have pcod. Lmp: 9th march to 13th march on 20th march (11th day of cycle) me and my partner had a physical contact. I had both my undergarments and a thin skirt on but he had no condom. A little precum fell on my skirt. I doubt I he had precum on his hand. There were 3 episodes of fingering on top of the skirt only. I also adjusted my clothes from top only. I took ipill within 35 hrs. I was spotting dark red colour from 2 days and had ver little flow and tiny clots in the morning and nothing now. Is this implantation? Any chances of pregnancy? Got a bhcg yesterday (one week post encounter) value is <0.200. Should I repeat again?
