Prenatal vitamins confusion

Olguita

Hi ladies:)

I'm 7weeks +3 and have been taking folic acid pills since 3 months before I conceived.

Since I know that I'm pregnant, I'm taking prenatals that have the typical mix of folic acid , vitamins, iron, omega etc.

The folic acid content is 400 in the ones I take. Today a friend of mine , who is also pregnant and already has two kids , said to me that I'm doing it wrong, as now apparently 400 is not enough folic acid anymore and I need around 1000 per day?

I'm confused, as I won't see a doctor or midwife until I'm 12 weeks (it's like that in the UK) , so won't have anyone to ask except Dr.Google 😅 I just find it confusing because why would they sell them the way they to if they wouldn't have enough folic acid ?? She just made me insecure.. this is my first , so I have no idea what I'm doing
