We planned to. 1st baby took 8 (various) rounds off meds and 5 IUIs (like your, totally unexplained; guess was endo, which c-section seemed to confirm), so I weaned at 15 months so that my period would come back and then planned to go in claiming we’d been trying to conceive for 6 months as soon as I had 2 normal seeming periods in a row at a normal interval. Instead, I got my period once (not even a normal one; way lighter than usual) and then got pregnant! So don’t give up hope.
