me and the love of my life need prayer for our journey of conception

He's so amazing in every way and feels the same about me in so happy to have found him, we've been together for almost 2 years now. We've been trying to conceive a baby for a bit been talking about it a lot we both feel the other would be great parents. And I so desperately want to conceive with him. He's 43 now and I'm 23 now. So I know it's a 20 year age difference but when we are together we and no one else even see our age difference. We just perfectly sync and I'm an old soul and our mental ages click perfectly.  If there's any tips anyone has on conceiving please help in giving me those tips and please pray for us. He's childless due to the fact his ex was super crazy and he never wanted to have a child with anyone other than me or wanted to marry anyone until I came along. Please help pray for us. We love eachother so much we want to turn that love into a baby that would be sooo incredibly loved by both us and our families. Our families both support us and love us being together. Because they can see how happy we make eachother and how good we are for eachother. I love him more than anything. But I feel our time is ticking away :( and I may have some slight endometriosis and that worries me, his mother has even told me "he just wants to have a baby(with me) so bad" I want to give that to him bc I know we would both be such amazing parents. Thank you guys!
