Pregnant?

I have been feeling off I'm 11dpo roughly my breast are so sore they feel like they are engorged like when I was breastfeeding I am getting vfl on all test and today I went to bathroom and had one small brown blood clot and a little brown blood then nothing. It's never happened to me 6 kids and 35 years old. Could I be pregnant or is this something else. I know I should know but I don't because I've never had this happen. Ive had labs done just waiting on results just hoping someone has experienced it
