Postpartum pain

I am 3 weeks postpartum. I had a vaginal delivery and I am in quite some pain. Birthing a baby did a number on my whoo ha. Ended up with a 2nd degree tear inside my vagina. When I went pee the last time i noticed like a beige colored mucus on my pad. It wasn’t a lot but I did stop bleeding already it’s just really painful down there. I really haven’t been over doing it, just been taking care and loving on my baby. I’m not sure why I had some discharge I’m not even sure if its normal. There’s no odor. I did have a yeast infection that has been treated already. I know it takes some time to heal my baby weighed about 8 lbs I just really don’t know if any of this is even normal :/
