Should Progesterone be checked with each Beta Test?

I only have it with my first beta, My RE did not even request it, I marked it on the form since I thought it was interesting to know

It was 23, beta was 1,176 (19DPO),When the nurse called I asked her about the # (23) and she said it was fine

I had a second beta 4,156 at 21 DPO ( No progesterone test)

Since then I have not had it re-tested

I went in for U/S 7 weeks 3 days and we saw the HB at 132

Now I know the internet can be helpful but scary too, I am reading all these horror stories about women who lost babies due to low progesterone, now I am freaking out-

I am 8 weeks almost 4 days.. nest U/s is next Wed.

Should I be concerned..
