Iām 28 & currently pregnant with baby #1.
The most important thing to me was getting married, which I did at 25. After we got married, I really wanted to finish grad school before having a baby. We did start TTC while I was still in school, once weād passed the point that I would at least graduate before the due date. That wasnāt the original plan, but COVID pushed my graduation back a year & we didnāt want to wait any longer to TTC. We started trying in September, I got pregnant in April, & I graduated in June.
Things like job & location are important, but for us much of that has settled for the better while Iāve been pregnant. My husband just started a new career thatāll be much more stable & the job switch allowed us to move closer to family. And now weāre in a more affordable city, so we can rent a 2bd apartment which is so much better than our old place. I suppose itās a bit different when going the IVF route (because of medical whatnot, the cost of it, etc.), but generally Iād say donāt feel like you have to have everything perfect before TTC.
Summary
When I was 24, I found out that I have the BRCA2 mutation so I have a very high chance of getting breast cancer & that risk would really kick in once I turned 30.
So in the appointment, the doctor asked me if I wanted kids. I said yes & heās like āGreat, donāt let this diagnosis stop you from having kids if you want to. But what you need to realize is that, if you do get breast cancer in your 30s, you will most likely survive it but you will almost certainly lose your fertility due to the chemotherapy & radiation that you would need to survive the cancer. So, if having kids is really important to you, then you need to start having kids before you turn 30.ā
And Iām like āWell, Iām not married yet. I donāt even have a boyfriend, soā¦ā
The doctor says āof course, Iām not telling you to go out & be foolish. Thereās things in your life that will have to be in place first. But you have to understand - if having kids is truly important to you, then you absolutely must start trying to conceive during your 20s. It has to be the priority. You donāt have the luxury of waiting until youāre 35, or even 32, because thereās a good chance you might be infertile by then. So whatever needs to happen in terms of dating or marriage before you can have kids, thatās something that needs to happen sooner rather than later.ā
So anyway, I was 24 then. I really didnāt know anyone I was interested in dating & I didnāt think Iād really meet anyone for a while just because of where I was in life then. I started thinking that maybe Iād never get to have kids. Well, a couple months later, my cousin set me up on a date, literally my first date in over 2 years at that point, and it worked
we dated a year before getting engaged & then got married 4 months later.
Anyway, it just kinda struck me how youāre 24 & figuring youāll be a smbc because it made me think back to me being 24 thinking Iād never be able to have kids because I didnāt think Iād get married before 30. Now Iām 28, married, & pregnant! Things can change so quickly 
And also, most of the checklist goes out the window when itās really a matter of ānow or maybe neverā. Otherwise, I wouldāve wanted to be more established in my career before TTC, have more savings, bought a house, etc. But none of those things are as important as being able to have children while I still can.
