Is it ok to take 2 multivitamins + iron,ascorbic acid 500mg,and folic during pregnancy?

Probably: I'm not sure if the vitamins you are taking are specifically pre-natal vitamins; it is good they contain iron. You should compare a label of pre-natal vitamins with what you are taking to make sure they are roughly identical. Probably don't need two! The folic acid is fine. You likely don't need the vitamin C as it is probably in your multiple/pre-natal. Too much can be harmful. Best wishes:)
