Pre-natal vitamin advice??

Bri • pregnant with a baby girl due April 2021 🎀 FTM, 24 years old

My partner and I are starting to TTC and I’ve also just started taking my pre-natal vitamins. We aren’t properly trying until after a pre planned holiday in April, however we aren’t being careful either.

If I get pregnant within the next month for example, will the pre-natal vitamins still help or should I be waiting to try until 3 months after taking them? I will continue to take them throughout the pregnancy (when it happens).
