Help!!

I took 3 pregnancy tests 2 days apart each and I got a second like immediately…. On each one The second one was darker then the first one… and then the third was darker then both so today I take another test… just to be sure and then nothing… no second line So I did 2 more today and again no line on either of them…. What is going on am I pregnant? Am I gonna miscarry if I am? Did I get 3 false positives?

There are the two darker ones out of the 3 on the bottom and then the 2 tests I did this morning with no second line on the top… wtf is going on I feel crazy…
