How long trying before using my frozen eggs?

I‘m 41y old and trying to get pregnant with my first child. I always took care of my body, no smoking, no drinking, very healthy diet and dancing/yoga a few times per week. My cycles are on point, 28 days, ovulation at day 14m, AMH is good.

Trying it for 4 cycles now (my partner is 37) and so far it didn‘t work out… My doctor said we should try for 6 months, then we should use my frozen eggs from age 36 to do ICSI.

Is or was someone of you in a similar situation to decide if the frozen eggs should be used rather sooner than later?

Looking at the statistics with a 7-10% chance of a natural pregnancy per cycle in my age is rather demotivation🙈 I want to keep a positive mindset, also because my grandma was 45 when giving birth to her first child - and that was already 1950😄
