Trying for baby #2

Hi! My son was born March 22nd, 2018! So he’s almost one. We just started trying for baby #2. I ovulate on the 12th so we started BD on the 7th then we’ll BD the 9th, 11th and 13th! With my son I got pregnant the first try (and we weren’t necessarily trying (just stopped not trying). I’m still nursing him (morning, afternoon & night) but my period came back in January and 31 days later my period came in February! I know people have a hard time but I’m so nervous it’s gonna be hard for me to get pregnant the second time. Can anybody give me some personal stories of getting pregnant with their second!? Thank you!
