Confused, Worried, Wondering!

I found out on Sunday that I am pregnant! Now it's Tuesday and the Cray Cray I am decided to take another test! I took those strip tests to begin with and it showed a line almost immediately but vvfl. I got an Frer with the two test pack, digital yes + and the one with the two lines showed an extremely faint line, almost non visable! So this morning I took another of the strip tests I had... barely visable line.. now I'm freaking out cuz it feels like this pregnancy is not sticking. I haven't called the Dr yet either 😞
