Coffee when TTC?

Rebekah • Hubby and I have been together 11 years, married for 4! ❤TTC baby #1!!!!👪
So I've heard you shouldn't have a lot (or any) coffee while pregnant, but what about when TTC? I'm starting today with only drinking one cup of coffee in the morning, instead of also bringing a travel mug with me to work and sometimes having another in the afternoon. I want a baby so badly and I'm going to try everything in my power to get pregnant! If less caffeine helps, then I don't mind sacrificing! What are your opinions/suggestions/recommendations??
