Anyone else pregnant & breastfeeding?

Jess • Married to the love of my life, totally smitten with our little girl and boy.
My daughter is nearing 11 months and I'm 4 weeks pregnant. I have a little over a month to make it to my goal. Anyone else?
Will my supply dwindle that early? Luckily some nipple soreness and a loss of appetite are my only issues so far. Hopefully it stays that way. 
Anyone have any advice for the next month, or in the same boat?
