I am having lighter than usual periods (colour and quantity both) this month. Last month my period date was 26/02/21. So I was expecting before 26/03/21. But this of month my period date is 26 march and it is lighter than usual periods (colour and quantity both). On 12 march I was with my partner. We were making love but we didn't did sex, but his penis was just touch my vagina entrance he trying to do sex but we didn't did. So there is any kind of problem happening because of that moment or it is something else. We didn't use precaution at that time. And one more thing my period was irregular before 3-4 month by last 3-4 months I was having regular periods. So please tell me why I am having this month this kind of periods. please help me and please reply early as soon as possible.
