Period after breastfeeding

Dana ☀️ • 32. Married 7.12.13 • Mommy to Elliott 👧🏼 3.5.16. Due with baby girl #2 12.12.18
I had to quit breastfeeding for multiple reasons, but I'm question how long after I quit breastfeeding should I expect my period to come? I haven't breastfed in 3 weeks.  I am currently almost 12weeksPP.
