from brown to pink

Felicitas

Okay ladies help me understand I had an ugly brown discharge for 8 days no odor only noticeable when wiping...I had a light pink spotting at 8 I went to the bathroom and notice more pink when wiping...at first the brown discharge I thought it was a period but then maybe ovulation but now pink I have a left pain not bad kinda light cramps I'm very irregular though...what is my body going thru?
