Help?!

So I just had my son 5 weeks ago, my husband and I had sex for the first time since I gave birth. And omg!!! It was very painful! I couldn't handle the pain that we had to stop. 
Is this normal??? Is this happening to other people as well??
And how long before it stops hurting?!
(I know it's not because of low lubrication, because I was extremely wet☺️ I know tmi)
