The reference book I use to look up drug depletions, does list combo birth control pills (both estrogen+ progestin) as depleting B12. It lists all the B-complex too as affected. So a B-Right complex by Jarrow, may be needed too.
So you will have to supplement well, and then get retested in 3 t 6
months. Stop the supplement for at least a week, before retesting.
Your level is not dramatically low, but it is low enough to pay attention to. 400pg/ml is the new low, but the labs have not changed the ranges still after 10 yrs.... and lows of 200 are still considered by doctors as "normal" because a red flag doesn't come up at those low levels.
Some websites exist now on this topic, B12 deficiency and drugs:
