Baby measuring behind?

Karin • Isabella 12/31/17 💖 Cora 👼 Baby 3 Due 9/8/23

Currently 22w4d but measuring 5 days behind? my high risk OB didn’t seem too concerned yet? Anyone else in a similar situation? he said me having a mthfr mutation can cause the placenta to become lazy and slow nutrition to the baby?! Never had this before so slightly worried… had a stillbirth last year at 29 weeks! Baby girl has a beautiful working heart and no genetic/organ abnormalities!
