TTC baby no. 2

Went to the doctors for my 1 year postpartum check up and she told me I was perfectly fine and ready to have more! TTC baby no 2 (going on month three!) and I’m nervous there’s something wrong with me because I can’t feel myself ovulate after my csection! I trust my doctor and still think I’m pretty young (26) to get pregnant. Idk why I’m in my own head thinking negatively. Think I might use opk? Advice / comments!
