Thanks for your query.
Normal with a increase of age ovaries volume decrease and the number of oocytes is decreased and the chance for pregnancy
is more low .
You should have intercourse 48 hours before the ovulation day because the chance is greater.
Fibroids do not interfere with the fertilization and do not be worried for this.
You should take in consideration and IVF if you do not conceive recently.
Take care for your self and do not lose hope
God bles you
