OTD positive

OTD was yesterday and it’s positive. I’m happy but scared, I’ll be 39 when it’s born (if all goes well). I had ivf on the nhs in the uk in 2015, we only retrieved 3 eggs. All 3 made it to day 5. One was fresh transfer and is now my 4 year old son. One was frozen and the other was donated to research as it wasn’t developing right. We weren’t sure whether we wanted another child but the frozen embryo always left a seed of doubt so we figured we’d try it now before we’re too old and it’s worked (so far). Still early days obviously.
