TTC & Breastfeeding

So I’m currently 10.5 mo PP and we’re trying for baby #2 already. My cycles have NEVER been regular & the month we convinced I was prescribed Provera & then Chlomid & she recommended we use pressed. First month trying all those and we got pregnant! But b/c I’m still nursing my first born my body isn’t ovulating regularly & I can’t take those medications. I planned to stop nursing at 12mo or at least wean, & then go straight into the chlomid & provera cycled. Anyone have success while TTC & breastfeeding? I didn’t want to quit, but I want another baby. What about tips on relactating, or nursing my oldest again once new baby finishes colostrum.
