Spotting/discharge at 8 weeks

I’m 8 weeks pregnant and I’ve had spotting a couple times two times it was due to sex and after that it happened once more but I didn’t have sex it happened after I used the restroom #2 and it was only a little bit my spotting has been super light pink and never fills up my pad. I’ve been feeling like my vagina is super wet and then I get this like brownish discharge thing. I haven’t been having cramping just like pains /pressure on my sides nothing too painful and baby is in my uterus so I know it’s not an ectopic but wanna know what this discharge is due from?
