Light Blood Stain on my undies

Not normal. Bed rest ka then sabihin agad sa ob mo pag check up mo. Or much better kung contakin mo na sya to inform. Ganyan din ako. More than 3 weeks din akong may spotting konti lang din light brown. May subchroionic hemorrhage daw kaya need ng bed rest at pampakapit. Check up ko na din this Saturday feb. 6
