in need of 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.
So chances are I'm probably out this month.. That's ok. What can I do or buy to up my chances?! I have OPKs, getting a BBT thermometer, getting more preseed. Anything else?!
