I have a weird lactating history...I started getting milk when I was 7 months along with my first. I nursed him for 13 months, and obviously had milk that time. I pumped 4-5 times a day, plus nursing at bed and morning and afternoon, all year. My periods started up within a few weeks of starting solids. I continued to have milk that I could express until I miscarried when my son was 2 years 2 months, and I was very dehydrated. I got milk back in (full breasts and everything) several days afte rhte miscarriage. I continued to have milk I could manually express (just a few drops) through my pregnancy with my next son, whom I nursed for 30 months. With him, I did my postpartum bleeding for 5 weeks, and then we moved into a new house two weeks later. I started bleeding again, thinking I had pushed it too much...but then I realized I was feeling rotten...bleeding...and had my period 8 weeks after giving birth. Frankly, it sucked. I had it regularly after that--but tried for 8 months to get pregnant, and could not (when previously it had been very easy) until I completely weaned. Now that I'm pregnant again, i have absolutely no milk, from the week I weaned onward. And, obviously, no periods. :)
