Getting pregnant in less than a year after a c-section

Elizabeth
Hope soon and did you have any issues? I know it's recommended to wait a year. At least that's what I was told. I'm a little over three months postpartum and we would like to wait a year to try and have another. I have the Nexplanon (arm implant) and I'm so tired of spotting all th time. I haven't found another control that fits me well. I've tried this, pills and the shot. I end up getting really bad headaches, break out, pissed all the time, or spotting. We may end up just being careful with condoms or something. But if I were to get pregnant before then, y'all think it would cause serious issues?
