First time TTC!!! Advice?

Valerie
My husband and I are 25 and TTC #1. Does anybody have any advice that might make this less daunting? Or even some encouragement. I have PCOS, but on the very light end of the spectrum, so it shouldn't affect conception, but I'm pretty nervous. My cycles are like 39 days, so that concerns me, too. Toss your wisdom my way! Thanks!!!
