Please my last period ended on the 19 of August then I saw my bf on the 21st but his sperm was just right on my vag and I wiped it off then on the 9th of this month I was bleeding like my normal period but was supposed to come in the 12th. It ended yesterday and All of a sudden I'm seeing little blood again today. Is it possible I'm pregnant? I'm so scared I don't know what to do.
