Hi K., once I dropped to one feeding/day, I noticed my cycle starting (i.e., change in discharge). I believe my period started about 4-5 weeks after I noticed that change. I did completely wean my son during that 4-5 weeks, but I believe the cycle/hormones started shortly after dropping to one feeding. Years ago, I did not start my cycle or period until after my first child was completely weaned. I used a charting system when I was trying to conceive #2 that relies on discharge. I don't chart anymore, but it has been very helpful knowing the signs to look for regarding my cycle. I would recommend it for anyone wanting to get pregnant or not wanting to get pregnant.
Good luck!
