Fertility clinic IVF specifically

My name is Edna Jones, I will be 45 years old this coming April. I had my tube tied in 2012 when i had my baby girl with the hope of not attempting to get pregnant again. Unfortunately i got divorced and couple years later i married my now husband who desire to have kids. I tried to get the tubal ligation reversed but my OBGYN advised i should go the way if IVF because of my age and the chances of pregnant. My insurance refused to cover for the treatment and is very expensive. That is why i am reaching out for help to have another chance of being a mother again. Nothing is too small as a little will go a long way. We thank you very much.
