@SadTexanChick Here's a different perspective.
After years of relentless Tinder matches and never having a relationship lasting more than two weeks, my BIL met a woman in her early 30s who I am fairly certain was "on a timeline" like you.
He was about to turn 30, had many many notches on his bedpost, but no relationship experience, and had decided it was time for him to grow up and have a serious relationship with a serious woman.
The woman he met seemed to fit the bill. She seemed like a real grown up, with impressive academics, a proper well paid career, already a home owner in a major city, good relationship with her parents and siblings, very clear that she wanted marriage and a family within a short time.
He no doubt found her attractive because he had never struggled to attract women and although he had had a lot of casual sex with a lot of more conventionally attractive women, I am sure he would not have chosen to marry someone he found unattractive.
They were engaged within the year, married six months later, she got pregnant on their honeymoon and they now have three children. On paper it has worked out well.
In reality she is an absolute nightmare who has ruined various important family relationships and our relationship with BIL is very strained as a result of her behaviour. In hindsight, I think there were various behavioural red flags even before they got married, which he either missed or chose to ignore. And now the family is stuck with her forever because she is the mother of his three children. I don't believe he can really be happy with her but he probably feels at the moment that getting divorced would be worse than remaining married to her.
I completely understand that women in their 30s have a limited window of time in which to meet a man, get married and have children naturally. At the same time, I would always discourage men (and women, for that matter) from marrying and having children with someone they have known for so little time. It's just not long enough to work out whether you will be compatible in the long run.
In your position I would look into freezing your eggs (or even creating and freezing embryos with donor sperm) and relax your dating requirements.
Maybe you'll meet someone and it will all work out. Maybe you won't. But you can't force it. Some things just aren't within our control.
For balance, I also know a woman who met her husband at 38 and went on to have three children naturally, and I also have a close friend who met her partner at 35 and has struggled with her fertility but is now pregnant with an IVF baby.
