I would call your doctor just to let them know, my doctor always said that unless it was bright red or I was having pain then it was normal. but if you notice that it isn't going away you might have a UTI or kidney infection
I WOULD BE SAFE AND CALL THE DOC!!!!!! THIS HAPPEN TO ME AND I WENT TO THE ER THEY SAID I WAS FINE I WENT TO THE DOCTOR THAT MONDAY AND THERE WAS NO HEART BEAT I WAS 12 WEEKS, IM NOT TRYING TO SCARE YOU IM JUST SAYING YOU SHOULD CALL, I HAVE A BLOOD DISEASE THAT CAUSED MINE BUT ANY SITE OF BLOOD I WOULD CALL THEY TRIED TO TELL ME ITS OK AS LONG AS ITS NOT BRIGHT RED OR A FLOW BUT THAT WAS NOT TRUE FOR ME, WHEN I WIPED IT WAS LIGHT PINK
