I was single and in my early 40s when my biological clock went off. A little late to conceive, but try I did.
From 43 to 46-years old, I had 6 inseminations using unknown donor sperm and my eggs. When that didn't work, I went through 2 rounds of IVF. When IVF didn't work, I enlisted my younger cousin to donate her eggs to me because my mine were probably too old.
Even with her 20-year-old eggs, I still couldn't get pregnant. I guess it wasn't meant to be. She was a champ though, and I'll be forever grateful for her generosity and support. She was part of an important journey that I don't regret for a minute.
