Okay so I posted on here the day before yesterday I had light bleeding.. Well the next day yesterday No blood at all my period is due tomorrow and is always regular. Today I started lightly bleeding again just pink water with some CM in it. I woke up with a busting head ache and sick to my stomach BAD!! I have had like 3 drops on my pad all day.. I'm so confused is this my period there's no chunks or blood no bright red blood just pink watery looking blood with a lot of CM! I'm cramping super bad and with my period I always start out heavy like it covers my underwear I just don't understand what's going on right now.. Can someone please help should I call my doctor or what?
