Hi momshies i need your answers please. Ty po

Cs po ako last december 20 i had light blood flow on january for 5 days then pag dating nang feb. Di po ako dinalaw tas this month po nung march 8 nag sex po kami ng husband ko withdrwal and then kahapon po may light blood flow tas nag change ako nang underwear then wala na pero bumalik po ulet today & still light blood flow.
