Had baby in Oct trying now for baby #2

Martha
It is hard to know when I am ovulating using this app because I have not started a normal cycle yet. Does anyone know when I should start the bd? I read online if I breast feed it takes about 6 months to get back a normal rhythm. But I have met other moms who had baby #2 right away. Does anyone know how I can get my body back on track for baby #2. I currently am 2 pounds away from prepregnacy weight. And I am eating right. I also wont give up breastfeeding. How did those other moms do it?
