Everyone's different but might be worth getting checked. For me it turned out I had some old accumulated blood stuck inside, possibly from a bit of placenta left, & had to have a D&C 5wks after the birth. Obviously you want to avoid any kind of infection "down there". Try to avoid plastic-backed sanity protection just in case until you know one way or the other, as the plastic keeps the area warm & can encourage infection. Maternity pads are made of breathable material so are much better.
