TMI! I need advice !

I just had my baby a week ago and the first day I was able to poop perfectly fine. Now I am 8 days post partum and since the 7th day I’m not able to poop comfortably. Like I have to go really really bad but my poop has gotten hard and it hurts to push it out. I could be stuck in the bathroom for like an hour before it comes out. Then when I push my vagina hurts and my butt hurts too that the pain is causing me not to go. I have been taking stool softeners and I am lactose intolerant so I’ve been drinking milk and tons and tons of water too. I don’t know what else to do I’m going to call my doctor soon but what do y’all recommend for I can poop. Please help 😢
