Fant pregnancy test

Okay so since last sat I've Ben getting a fant yes on my pregnancy tests and some no's on them when I went to the dr they did three tests one no and 2 yeses I go back in on min for another pee test. It's just at this point I don't know what to think about it all I'm late for my period but still a tiny line if I'm right I'm about 4 weeks if I am what do you all think?
