it all started two days ago till today. AF isnt due till 7th

Sunday I had some light pink blood after wiping and the same as Monday.

Today I had brown when I wiped.

tested today and it was negative.

had a little pain at the end of peeing. but all ended today.

had mild cramps and headakes a little with sore boobs but thinking that could just be bc AF is coming. I'm going to try and make an appointment Friday.
