Sex after pregnancy

Azize
Hello ladies
I had my baby on 3.5.2016 💖
It was a natural birth and i only had 1 stich. 
My stich is off already and my bleading is stopped. I just wanted to ask when we can start having sex ?
I did ask my midwifes and one said i have to wait 6 weeks and the other one said i dont have to wait 6 weeks now i am a bit confused :/Â
