advice!

Brandi • My name is Brandi and my fiancé`s name is Joe. I`m 23 he`s 25. TTC baby #1. I`m a hair stylist and he`s in flooring.
Me and my fiancé are ready to start actively trying for a little one! I'm going to start taking prenatals, should he be taking anything that can help? And I've heard good things about preseed, what does everyone think? Anything better than that out there? Is there anything else we can do to increase our chances?! Any advice is welcomed! Please and thank you!
