How long?

Shonise • I'm 25 years old. I have a 3yr old daughter and a 9yr old son. I'm happily engaged as well! Nd now pregnant with my 3rd!
ive always been skeptical about how long im going to start back having sex after birth. I just had my son jan 27th, 2016. I told my fiancee theres no gurantee if we are going to have sex after my 6wk appt. This was my 3rd pregnancy. With my first two i waited almost two months after my 6wks to start bk. Thats just me so i wanted to know how long do some mommies wait to have sex again after birth & your experience? (if you dont mind answering)
