Any progression?

I got my first BFP last Friday. The tests, regardless of brand, seem to be progressing pretty well, until this weekend. Back in March, with my last m/c, all brands got even darker than the control line. This time it seems the tests are kinda staying steady. Today’s almost seems a little light, on both Accumed and FRER. I know a lot of people say to not even pay attention to the darkness of a line. I get it! But, I’ve seen what these tests can do. Granted, I lost that pregnancy. So then, what does that say for this one?

My first BETA was done yesterday. I go for a repeat on Monday. If those numbers are good, I’ll for sure feel more at ease. It’s just a little concerning to see that the line hasn’t darkened, and arguably has lightened, after three days. All tests were taken with FMU, under almost identical circumstances. I guess after being pregnant four times in one year and losing three of them can make you a little bonkers. Thanks for any insight!
