Ok so around 8dpo I noticed I was feeling a bit off and when I went to the bathroom I wiped and it looked like (TMI) clot like gooey with yellowish and white egg like stuff and in the tip it had a little bit of blood which was a little red and brown that was the last and first time I ever seen that..after I began getting a bad migraine ! Which I never get and lasted all day, along with a bit of diarrhea ..2 days prior I had some diarrhea as well. I’ve taken 4 pregnancy tests and all came out negative I took 3first response one digital when I was 7days late ..today I’m 9days late ..there’s days I feel like AF is coming but doesn’t show up
