Pregnant for 1 month, do I still need to take folic acid from now on? Can I eat fish?

Patient's question:

I heard that eating fish makes chickens transform their eggs, is that true? Is it too late to supplement folic acid now? How should it be supplemented? Thank you!

Doctor's answer:

Pregnancy at 1 month should be around 4 weeks, and it's normal to supplement up to 8 weeks. You can get a prescription from the maternal and child health center, as they usually have those low-dose folic acid supplements.
Fish is fine to eat, no problem.
If you find a satisfactory answer, please adopt it promptly so as not to disappoint the responders!
