Honestly, the chances of a natural conception, or an IVF baby with your own eggs, are miniscule
By 45 the chances of a natural conception are around 1%
The chances of a miscarriage are over 50%
The chances of a baby with a donor egg are excellent - it's like being in your 20s
I say this not to be cruel, but to provide some context
Fertility tests will show if you're ovulating and how your ovarian reserve is looking, they won't say anything about egg quality which is what counts. And unfortunately the best test of egg quality is age. Even at 30, only about 1 in 2 eggs are chromosomally normal. This goes down to less than 1-2% over the age of 45
The spate of celebrity women in their late 40s having babies creates a false picture of fertility. They are without doubt having donor egg conceived babies. Which is wonderful! They are having much longed for children and medical technology is enabling them to have happy, healthy babies who are deeply loved.
I wish you all the very best with your journey x
