Weird things going on

Ashlyn

Hey girls, my very last period was last month & it was just brown the whole time. Except for my 2nd or 3rd day where it was deep red before continuing with brown. I had no cramps. Now I’m 20 days late. I took a test on my 13th day being late & it was negative. I cramp here & there every other day but still nothing. I’m not on birth control & when I do have sex, I use protection. I’m very concerned.
