Getting nervous

I’ve only taken 4 test 1 Monday 3 on Wednesday. I’m starting to get nervous. I want to go buy more tests for my sanity but my fiance said to wait it out. My period was supposed to start on the 6th I’m now 8 days late. By now I’m having some kind of symptoms boobs are normally sore or something. I just have really bad heartburn but I’ve also had it the whole time with my daughter and after I had her too. And a missed period.

This is Mondays Test

These are Wednesdays tests
