I did this when I was 37 and in a LTR but wasn’t ready for children/wasn’t sure it was for us.
Research the costs and be prepared to exceed them. One cycle cost around £5K. It was more than anticipated because I needed extra/higher doses of the follicle stimulation medication. Then there’s a storage cost every year.
You need to be in a good place mentally. The hormone changes too bad for me but it did feel quite isolating as DP wasn’t involved at all (I injected on my own and he didn’t come to any appointments). Have friends/family to speak to - someone will need to collect you from the clinic after the procedure too.
It was a rollercoaster of emotions and the uncertainty of how long before collection/how many I’d get was quite exhausting (but didn’t hit me until afterwards).
I had borderline reserves and they predicted at the beginning I’d get 7 eggs. I got 9, which have a 20% chance of leading to a “live birth”.
Freezing an embryo gives better results, but that wasn’t for us.
Overall, I wish I’d done it sooner and think I’d actually have been stronger emotionally if I did it while single. I’ve not lost anything though and as it was covered by our health insurance, it was a relative no-brainer. Two weeks of disruption and the best sleep ever during the procedure!
Oh and I discovered MN during the process. There were so many posts about FSH levels, outcomes, experiences etc. Take a look at what others have posted before - much more useful than anything a dr told me.
