Hi I Am Hoping To Get A Little Insight Of

Hi I am hoping to get a little insight of what could possibly be going on with me. I have schedule an appointment with my doctor for this coming week. I am 30 years old. I have had 3 period like episodes in the past five weeks. It starts off as with a small amount of brown discharge the first day and into the next becomes a little heavier and red. At times I feel like a gush of blood rushing out but nothing until I urinate and its like syrupy blood. I guess that's the best way I can describe it. Day three and four are a pretty light flow and eventually starts turning brownish red again. I'm not quite sure what's going on.
