Really confused

I’m really confused, so I didn’t take a test when my period was due because I thought I have started early had what I thought was a pretty normal period, just a bit lighter and shorter, normal cramps and everything. But after my period finished ended I started to get sore boobs which isn’t normal for me straight after I finish, and feeling sick, I nearly had to stop the car to throw up the other day.

So I took some tests:

First one I took about 3 days after my period

This was the next day:

Then these two

Am I just going crazy?

I should be ovulating soon if this is a normal cycle, I just haven’t had this many faint lines before in every test I’ve taken,

I think it’s probably a chemical tbh.
