dark brown mentrual cycle from beginning

I started my mentrual cycle and it is almost black in color. I dont know if I should be concerned. 3 months ago is when it started but it has been getting worse each month. I know I have no concern about stds. had a pap smear not long ago been with the same partner for over a year. I have also been feeling sick. I dont have any extra painthan normal but I do feel bloated more than usual. back in january I had lasor pocedure done to remove abnormal cells in my cevix. The doctor said everything healled properly. Can someone tell me if it is normal?
