Breastfeeding and expecting 🤦🏽‍♀️

I'm breastfeeding my 12month old and I am currently 13 weeks pregnant. Does the tender breast feeling ever go away? It hurts SO bad sometimes, so I decided to wean her off. I thought it would be easier but I honestly think that both baby and I suffered equally from the process and I don't feel like I'm strong enough to stop. I'm can take the pain but I can't handle letting down my little girl if she wants to feed. Also, I get the feels pretty bad (hormones)... I'm just torn. What's going to happen when I get big?

I also heard that even if I wean her off she will regress once she sees new baby feeding. Is that true? I am NOT ready for tandem feeding... nope not happenin, I've seen it and it looks intense. Like, a 20 minute group hug, but more overwhelming. I don't know, that's just how it looks.

I told my doctor I am still breastfeeding but he's such a tool that he just wants to get his appointments in and out so he can get his money. I figured if he didn't say anything when I mentioned it then it must be fine.

Anyone with experience with this?
