Anyone breastfeed while pregnant? Did they naturally wean?

My 18mo breastfeeding more frequently now since I have become pregnant.

I am 6 weeks pregnant and my little miss has been cleanching her jaw once she falls asleep (OUUCCH) I am in so much pain!

I feed to sleep and feed all through the night!

I want to gently wean as im having severe aversions but she isnt having a bar of it and seems she feeds more!

Did anyones baby wean themselves during pregnancy?

Did you do anything different to get them to wean themselves gently?

I LOVE breastfeeding and the bond but I am in struggle town! Scared I will regret losing my "easy fix" to everything but ahh help!
