Wanting to get pregnant with artificial insemination as a single women

Y’all need to tell me if I sound crazy lol. I’m 23, I own a very nice family sized home alone, I have my life really together and a well paying career that I love with opportunities to promote to higher paying positions with more experience. Well since I was 10yrs old all I’ve ever wanted was to be a mom, it didn’t matter if it was through foster to adopt, private adoption, or becoming pregnant myself. Here’s where my issue lies though. Infertility and early menopause runs in my family. My mom went through menopause at 30 years old, as well as my grandmother. My father’s side also has their own fertility issues. I’ve been told that I am potentially on a time limit to have kids. I’d absolutely love to have one biological child but I have no partner to do so with, and even then I’d want to be married to them (I want no baby daddy drama if we don’t stay together) and at that rate I’ll be close to 30 bc I’m in no rush to be married. I would 100% prefer to do this alone as I thrive better independently. My mom did it alone. I already do everything alone while also caring for my 2 dogs, 1 Foster dog, and 2 cats. I am very well aware of how hard being a single mom will be but I would take that over not having any children. Yes I can adopt in the future but I’d love the experience of being pregnant, feeling the kicks, etc. Also, this is something I’d want to do when I’m 25/26.

So would a financially stable, healthy, owns her own home, but single 25yr old look crazy if she approached her doctor to try and get pregnant through sperm donation?

Quick update-

1. yes I have the financial stability for daycare as well as a nanny or babysitter if needed. I’ve done all my research into the expenses of raising a child. I have job security for maternity leave, as well as an extremely supportive boss and coworkers. Since this is years down the road, I will have plenty of money saved, on top of the money I already have saved, in case of an emergency, medical bills, losing my job, etc. The family that I still have in my life are extremely supportive and have been there to help care for my house and animals in the past when I was hospitalized.
