Implantation bleeding=pregnant?

So my husband and I decided to stop preventing pregnancy and just letting it happen. this month, we are moving so we only had sex once during my fertile period. fast forward to the other day, i wiped and i noticed some brown blood. I just ignored it but i knew it was odd. when i went to change, i noticed i actually had a little on my underwear.

it had to have been implantation bleeding because i don’t bleed irregularly and it fell between the 6-12 day period. so my question is, does implantation bleeding equal pregnancy? i know this sounds like a dumb question bc i googled it but i’m not getting a straight forward answer.
