It all depends on your recovery post c/s, if you had much bleeding etc.

My OB said as long as I didn`t conceive within the first 6 weeks post c/s, I could try when I liked, so we decided to start TTC after my post natal check up, I was exclusively breastfeeding but conceived 5.5 months post c/s, I then went on to have a VBAC.

Good Luck.
