TTC baby #2

I currently have a 2 year old and he’s the love of our lives! But my husband and I are ready to start trying for our second. I’m praying it doesn’t take as long as the first but I’m not sure what to expect. First month of tracking cervical mucus and TTC but no luck. It took us 9 months to get pregnant with our first. Advice: Should I start using OPKs? Should I not stress about it? How long did it take y’all to have your second given your first took a little while?
