Hi, I am 19 years old & 3 days late on my period. I have felt extremely weird the last couple of days. I’ve taken many tests. I took a blue dye test yesterday after i almost threw up all over my bfs car. And it was a faint faint positive. Photo below

I took 3 first response tests. Digital was negative. The dye ones were slightly faint but not really there. I took another blue dye this morning and it was even darker that now without squinting i can see the line. I am confused. This like post 3 i’ve made but at this point… i think im pregnant but some people say first response is the end all be all of results. Thank u for help.
