Blood after cervix checked

Im in my 38 weeks + 2 days and just had my cervix checked this morning for dilation.. After i got home, i saw my whole pantyliner was soaked with blood. Not spotting, but looks more like period (brownish red). My gynae told me i was only 1cm and still far along.. has anyone encountered the same? Is it normal after a pelvic exam? I called my gynae she told me to see if there’s any contractions or if baby is not moving i have to come right away.
