I'm sukriti (23 yrs), on 3rd july, 2019 I was with my bf. We didn't had the intercourse. He was in his jeans all the time but I was undressed. I was laying on him, and as we sit after cuddling for sometime, I saw his pants somewhere around the thigh, has the wet patch and I was probably laying on his wet patch (again reminding he was in his full two layers of cloth ). Thereafter I had my periods on due dates 26th july, 23rd aug, 18th sept. But this month i'm not down yet. Is this a cause of placental sign? Is there correlation with my missed period or that incident? My periods were a bit light in flow with clots for these 3 months. I don't have any thyroid issue or any menses irregularities before this. Please guide!
