Hi @LimeStork and welcome.
I've had two early losses and a second trimester loss, so solidarity and I'm sorry for your previous loss.
For me, there isn't a lot I can look to for comfort as I've been on the wrong sides of all the websites and stats thus far, and once you've been through it once in the second trimester, it's more likely to happen again, so I have to ignore those websites that give % of success rates as they don't apply. I've been the 1 in 4, the 1 in 30, the 1 in 100 and potentially 1 in 30,000 too, so I get the desire for a scan and some reassurance.
I'm consultant lead from day one this time and have been prescribed progesterone (though my progesterone levels are good, it will be more helpful later on in the pregnancy to prevent my womb from contracting too soon, hopefully). I think it's usually EPU or consultants who prescribe it, but that's because my GP won't have anything to do with pregnancy, so it might be different for you!
I'm booked in for two scans - one at 7 weeks for viability and one at 9 weeks for development. This is due to a previous MMC, but 7-9 weeks give a good indication. We knew at 7 weeks in our MMC pregnancy, despite our baby having a heartbeat, that things weren't looking good as the heartbeat was slow and it was measuring 10 days behind. A scan at 8 weeks would have shown the same, but most people like to wait for 8 weeks due to the stats that say miscarriage is less likely then.
Whenever you decide to go, I hope it brings you the comfort you need ❤️
