Close to giving up on our rainbow bfp

Sharon
I was lucky enough to have a beautiful baby girl a month before I turned 42. I want so badly to give her a sibling. I had a mc when I was 43 at 7w 2 d and have not been able to get pregnant again. I will be 46 in July so my husband thinks we should give up. Part of me feels selfish to want to keep trying knowing the risks and the odds of us getting pregnant are so low but I can't seem to let it go. I am the youngest of 8 kids so I just feel like she will miss out on the bond of having a sibling. She just turned 4 and when she asks me where her sister's are I just want to cry and tell her I am trying as hard as I can. I pray so hard for God to bless us with another healthy baby. I am incredibly lucky that I have a wonderful little girl and I hope I do not offend anyone that is struggling ttc #1. I am really praying that we will get our BFP this month. Any prayers or words of encouragement would be greatly appreciated. Baby dust to all of us trying so hard for our miracle babies.
