TTC NEWBIE!

Hello lovelys!! My boyfriend and I decided it's time for us to have a baby. We both think it'd be really good for us at this point of our lives. I was wondering if you all could give me a few tips! We've been trying everyday pretty much the passed 2 months. But I recently started using Flo, and today is my ovulation day! Also, we both smoke marijuana, could that effect his sperm count or me in any way?
