How long were you ttc before bfp?

Fina • Mommy of 2, one boy one girl
Hello ladies, I was just wondering for all you lucky ladies how long did it take to conceive? My husband and I have a 5 year old and I love her dearly but she was a big surprise. Were now trying for number 2 and it seems almost impossible. It's been 3 months and still nothing and I'm very irregular so it's hard to figure out when I ovulate.
