Evap or positive??

Okay a little backstory, in March I took a test on Friday and looked again at it Saturday and I saw 2 lines, it didn't look like an evap line so I tested again on Sunday and ended up with my bfp. (which ended in a mc 3 days after my af was supposed to be here)

The pictures are of yesterday's test, the second line isn't thin it's thick (today so far the test is negative)

I am 3 days late with no sign of my AF. I've been testing every day with just the cheap Wal-Mart tests until I can get fr Friday.

My boobs are killing me, there was a drop of clear liquid out of my boob, no real cramps but a little tight feeling, cm very watery and cervix is now soft and med height,

Advice please I'm going crazyyyy
