So I took my first hpt on Fri 10/6 and got a very faint line. After that I took 4 more tests and all had very faint lines. I was suppose

to start my period yesterday but it never came. I'm so confused and frustrated. I had just told my fiance after over a year of trying that I decided I don't want to have anymore kids (we have 4). I took another test today not with fmu but the line isn't getting any darker. I'm worried it's a chemical and I'm actually quite sad. It's making me think the only reason I decided to not have more kids is because I wasn't getting pregnant. Has anyone gone through this and ended up pregnant? The pic is the second test I took where the line is the easiest to see
