Does anyone know if it's safe to take Vitamin B12 while pregnant? Idk how far along I am yet I have to call my OB Monday I just found out Friday and I've given up my caffeine but I'm dragging so bad and have 2 other LOs that need their momma too. Zzzzzzzzzzzzzzzzzzz. 😴 I'm so tired. Last night I dozed off while saying my prayers and woke up praying about some lady's living room a few minutes later.
