Re: weaning to get pregnant??
It's common for your first few postpartum cycles to be different from your pre-baby norm. Longer/shorter/heavier/lighter. Give it a few months to even out, and don't worry about weaning. AFAIK, weaning/not weaning isn't going to do anything to change how your body "regulates" your cycle, nor does a "regulated" cycle really impact your chances of getting pregnant. Once your period is back, and has been back for a few months, your chances of getting pregnant again are generally not impacted at all, even if you continue to nurse quite frequently.
The 2 things I would suggest doing are, one, to start charting your cycle, and two, to think about seeing your doctor or midwife if things don't go back to a more regular pattern in the next few months. There are physical conditions- aside from nursing- that can impact both your cycle and your fertility.
