So this morning I had some vaginal bleeding I would say it was light pink , after that I started having contractions. The bleeding wasn't heavy or nothing but I been tracking my contractions at first they were every 10 min than they went to every 6-7 min , they been like that for the past couple hours now. I went to the restroom and on the pad I put on had some dark brown discharge ?. Any suggestion on what that is or what I should do?
