I'm 42 and want to have a baby. Is it too late?

Asha
I was married once before at a very young age and I have 2 sons who are grown now. I recently married this year and my husband and I want to try for a baby. We have been trying to conceive for a year and a half now and nothing. I'm ovulating because I menstruate every month at the same time, however I do have a couple of small fibroids that causes me to have periods heavier and longer than normal with terrible cramps. Is it too late for me?
