I always have irregular periods & I am an athlete. My last period was Dec. 18th-22nd & it was almost normal besides the fact it was kinda short & lighter at the end. This month on Jan. 16 I started having brown discharge & it stopped leaking onto my underwear for about a couple of hours after track practice but still there when I wipe. Jan. 17th, I used two pads all day & it was still mostly brown but occasionally red when I wipe. Jan. 18th, the first time I used the bathroom it looked like a regular period. It was red, had a blood clot, & was enough to fill a pad. About 5 hours later I went to the bathroom & it was a mix of brown & red & little less than earlier. For the rest of the day it was mix of red & brown but mostly brown. Jan. 19th, it is back at a "normal" period flow for me but when I first wipe it's brown & when I continue to wipe it turns red. I change my pad about 2/3 times a day. What's going on?? I'm not used to seeing all this brown..
