Folic acid question

Ok so my dr put me on materna. Which has 1mg of folate (folic acid). The dr and the pharmacist told me this was what was recommended. When I went and got my refill today. A different pharmacist told me no that wasn’t enough folic acid I should have been taking 5mg. But she said there is no point to increase now because I’m 12 weeks. I’m confused. What is everyone else on? And will this be an issue??
