Chemical pregnancy? Or just paranoid?

I have a 26 day cycle, very rarely is it any more or less. I tested on Tuesday with a Clearblue and thought I saw a very faint line within the 3 minute window. I rushed to get some First Response to double check and a very faint line showed up within the 3 minute window. I tested the next day (expected period day) with another FR and it was also positive, still faint but a little darker. On Thursday I tried a CBD because my husband was nervous about the lines being so faint and it was negative. After a lot of tears I read to try another FR, which was positive, and again a little darker. I tried a FRD this morning (now 4 days after my period was supposed to come - and 16 DPO) and its was negative. I’ve read a lot of people saying the digitals just aren’t sensitive, but I feel like at this point it should be positive. I’m thinking about going to an urgent care clinic when they open and asking for a blood test. Any advice?? Similar stories??

I’m including pictures of the first two tests I took that were positive and the other dye tests in the days following for comparison.
