I agree that it is weird your doctor did not discuss this at your follow-up appointment. I nursed for 11 1/2 months with my first and 13 1/2 months with my second. I took the "mini pill" or progestin-only pill both times with no issues. It is not known to interfere with milk production so is usually a good option for nursing moms. I started at my 6-week check-up after delivery but did not have periods until eight months to a year later. Nothing is 100% effective, so I chose to take pregnancy tests once a month anyway just so I didn't have a surprise later. Condoms are also always safe if you do not have any allergies, and you can start those without checking with your doctor. Even if you are breastfeeding, it is possible to ovulate and become pregnant very soon after delivery. I was a little worried at both follow-up appointments after my deliveries that we might have gotten pregnant, but thankfully we hadn't and I did start my birth control immediately. I suppose after this third baby I might ask my doctor if I can start the pills before my appointment since it seems we never manage to wait that long. Good luck, and definitely check with your doctor, who knows your health situation and family needs.
