12 weeks prenavit and fish oil sufficient?

hello everyone. i notice most of the mummies here have been prescribed obimin or other vitamins by gynae for 12 weeks onwards. however for 12 weeks i’ve only been prescribed prenavit(since week 4) and fish oil (just started). is it sufficient ? or do i need to self purchase other vitamin supplements separately? Thank you so much 😊 #1stbaby #12weeks
