Could i be pregnant

Julissa 👋🏼

Im 55 days late, at 30/40 days late I would get negative pregnancy test. & just of yesterday I thought I got my period but in my opinion its very light for my normal periods..... When i first wiped it was a medium red with a very small clot. The second time i wiped it was light pink. As of this morning their light brown to dark brown. Any recommendations ? Kinda hard to go t. A clinic with no insurance and low on $$. What could it be ??....
