Nag mens ng regular dalawang beses, maaari parin bang mabuntis?

So I had unprotected sex on april 2 then i got my period on april 12-15 (it starts off as brown discharge but gradually turns into bright red with clots when I pee.) Then this May 14-18, I also got my period, (the flow is stable and it could fill up pads, with veryy small clots.) So am I clear? Or is there still a chance that I'm pregnant?
