To eat folic acid or start taking vitamin?

Hi Mommas, my EDD is on 18th April 2023. Currently I'm on my week 11 day 5 based on this app. I didn't know I'm pregnant until week 8 , quite late because of irregular menses since young. I saw the doctor on Sep 8. So doc gave me 1 month of Folic Acid pills. And my appointment with KKH was on 13 Sep (Week 9 by then but not sure day what). I'm currently left with 6 pills left. When I finish the 6 pills, it will be week 12 Day 4 based on the app, which means week 12 day 5-7, I have no folic acid. Do I buy 3 more folic acid pills to complete or do I start taking vitamins for trimester 2?
