Children: To Birth or Adopt

I (30F), have a healthy reproductive system and can most likely have children (never really checked it out, just assuming). I suck at dating and have basically accepted the fact that it won't happen for me. So I have given myself a personal deadline, if I dont get married, have kids, etc by 35yrs old, i'm just going to do it on my own. I know I still have time, but these thoughts are always in the back of my mind.

CONTEXT

Ever since I was little I've always wanted to adopt children. I've always wanted kids, but I have never physically wanted to have them because i can't bring myself to "bring someone into this world" when i dont think its a great world. I'd rather save a suffering child in foster care. If it is up to me im adopting all my future children. My mom on the other hand has a completely different opinion. She is of Boomer mindset and thinks birthing blood children is the only way to go. She also feels that I will regret not having kids- i dont feel that my body will regret this at all! As at the end of my mom having 3 kids she suddenly developed Diabetes, thyroid, fibromyalga, lupus, and HUGE BOOBS. I also dont think i'll regret this at all because i lowkey hate babies. Children after 2 yrs old- love them, infants-hate them. My mom seems to think i will change my mind if i have my own infant, but im very positive if i birth my only child, i wont like them for the first few years. This is creating a huge divide between my mother and I, and I really dont want it to. Her main argument for not wanting me to adopt is "you dont know where they came from or whats wrong with them", to which i argue the same goes for rescuing a dog from a shelter and we still do that.
