Been trying for a year

I'm 41 years old, me and my husband have been married for 4 years now. I got my tubes untied last year of 2016. We've been trying for a year now to get pregnant 🤰. Ever since my Reversal my period hasn't been the same. I have told my fertility doctor about it and didn't give me nothing to get it back to normal. He said cause of my age and I told him. Ever since I started my period I've never been late. I have 3 kids and never had a problem with my period. He told me and my husband that we have to do the IVF, no hope for nothing all the money we paid. It just breaks my heart so bad cause i know my husband would love to have a baby of his own. He has none of his own. If anyone or anybody can please give me some advice 😞😩
