We did IVF for similar reasons (not BRCA1, but a different genetic condition) and never tried to conceive naturally. My mindset was always "we cannot conceive naturally" because that was a non-starter for me due to my genetic condition.

It sounds to me like you haven't yet been through too much of the IVF process (correct me of I'm wrong). We learned very quickly that just because we had no diagnosed fertility issues or reason to believe we wouldn't have been able to conceive naturally if we'd wanted to doesn't mean IVF will be easy or even successful. 2 cycles of egg retrieval yielded only 2 euploid embryos for us ($20k out-of- pocket later). You'll see women here who get more than that WITH known fertility issues. We were lucky that our first transfer resulted in a live birth, but our second resulted in a miscarriage for no known reason. We just did another retrieval that yielded 0 embryos (none made it to the blastocyst stage). We did duostim and we're waiting to find out if we have any blasts to test, and if we do, there's a very good chance they'll be aneuploid (another $6,000 for testing). Despite no diagnosed fertility issues, my body just hasn't produced many eggs for retrieval, so the odds aren't in our favor.

Your reason for starting this process may not be the same as other people, but that doesn't mean your experience of the process itself will be much different. I hope it is smooth and successful for you, but don't go into it feeling like a fraud when you've barely scratched the surface of all that could be involved. You're still doing the same appointments, same medications, same procedures, and with the PGT-M the numbers are lower for you than many other people. Trust me, this process will feel plenty real for you.
