Tests not getting any darker

My period is five days late today, which hasn’t happened since coming off of birth control four months ago. I have sore breasts & nipples, today I am very fatigued, and I’m experiencing cramps on and off.

I started testing using FRERs on Monday through today (Thursday.) If I test with FMU, I get a vvvfl, at the right angles. It looks almost like a shadow. Barely visible. If I invert the picture of the test, I can see it a little more clearly, but only just.

If I test later in the day, I get a blatantly negative result.

My FMU test today is no darker than Monday’s test.

Is it likely I’m having a chemical pregnancy? With my first child, I had a very definite positive. I’m very worried 😞

***EDITED to change that today is Thursday not Friday lol
