getting pregnant while BF and supply question

pregnantchick

hi! I have 2 questions and would love your thoughts/advice.

1.  I am 39 years old and just had my first baby on July 24th. I am still nursing at night and before I leave for work, then pumping during the day.  I still haven't gotten my period. I really want to have another baby and was wondering when I can expect to get my period - if I cut back on nursing/pumping, would that cause me to get my period faster?

 2.  Is it possible to adjust my supply so that I only nurse at night and stop pumping during the day? Or would that cause my milk to go away?

 thanks so much!!!
