Wanting another

I've heard the rule of thumb from my RN at my 4 weeks pp checkup was 15 months between babies. As in I could get pregnant at 6 months pp and probably not have complications. But will they make me have another c-section? She said no. But I'm not quick to trust most medical personal from bad experiences of misinformation.

We don't plan to try for more until I'm a year pp (end of January). I'm so fucking bummed I tried to have a 100% natural birth all for her head to turn wrong in the birth canal and having emergency c. All that pain just to be numbed to be cut open. I want a natural v birth so goddamn bad. I feel robbed. It's bad enough there's other reasons I'm so upset with everything surrounding my first pregnancy and first baby.
