Turning 43...too old?

Je
My ex and I were pregnant in 2015 and I was 41. It ended up being a tubal so the 1st time I was ever pregnant ended badly. March 2016 he ended up leaving. We stopped talking completely in July 2016. I was finally over him and January 2017 he contacted me again. We agreed that we could never have what we did before, but he knew how much I wanted a baby and said we could try again. NO ONE would ever ACCEPT this baby, but I'm I too old to even think about this? I will be 43 next month.
