Need opinions and experience!

Judgement and nasty comments will NOT be tolerated!

My SO and I literally just started TTC and I use medical marijuana for extreme pain from a car accident......well, I’ve really eased up on it since the other day(I had my IUD removed Thursday so we could start trying) anyhow, this will be my third child, so I know every other risk in the book but not much about this.....also, marijuana while breast feeding?! I know for sure I will be breast feeding, so what is the risk then?

I’ve googled and of course there is close to nothing about this...so thanks in advance to anyone who has experience or help in this department!
