We kept putting it off too and likely would still be don't so except I started peri-menopause with severe symptoms and hormonal migraines 16+ days a month.
I was 28 when this onset and 29 by time time an endocrinologist finally told me that process of elimination meant hot flushes, night sweats, so on, meant I was likely going the way of my maternal family. Youngest menopause onset, final period aged 35 and oldest onset final period aged 45.
If you've been on hormonal treatment like the pill you'll have had no way of knowing if you're one of 100 who goes before age 40 (NHS website gave the stats), until you're off medication and have troubles.
My case was magnified because no conception, and following a tubal check both failed the dye test. Probably due to scar tissue of untreated endometriosis in my teen and young 20's, I'm guessing. Anyway, we were scheduled for laproscopic check prior to IVF when I came up pregnant. The wait time for the appointments, the tests, the appointments again, more tests, means you're waiting a year+ before you even know if there's a physical problem and if you're a good candidate for assistance.
Frankly, it's a terrible time and you might as well do the fun things you want to do while ttc. I wish I could have, instead of being housebound in severe chronic pain.
You might get lucky and get pregnant easy. But you also might end up waiting over a year while nothing happens and face agonising emotions during that period. I know I was appreciative of distractions. It's why I started a part time MSc once it became obvious there was trouble, and my condition meant that my previous job I was no longer physically capable of performing anymore.
Long story in my case. Probably won't happen to you. But it's probable that you'll take 4-6 months to conceive, too, and the doctors won't be concerned until a year's gone by.
So give it a think. The stats are on your side until mid 30s, but the time will zoom by, and then every month counts.
