Is this progressing enough?

Angel • Mommy of an angel baby girl 11.08.19 👼🏻 Rainbow baby boy born 01.30.21 💙💙 baby girl due 05.10.25 🎀

The first test was taken on 12/15

The last test was 12/22

I haven’t tested in between, I just never got the time (super busy)

I feel like it should be darker with all the time in between. I don’t know I’m a little on edge. I haven’t had the best track record with pregnancies
