Hello. I am 28 years old and I am concerned about bleeding that I've been having. I had a regular period for 4 days three weeks ago. Then a few days later I got this light bleeding. It started brown then went to light pink, then it would go away for a day or a few hours then come back again, its been 10 days now and the bleeding is heavier sort of like a normal period. I took a pregnancy test and it is negative, but me and my boyfriend have intercourse unprotected daily. Please help me and tell me what this could be... thank you.

IT is really hard to say what this is. If you have this amount of bleeding for this long then you should go to a doctor. Quickly.
