Hey, so sorry for your losses, I know how heartbreaking it is as I have also had 2.
My first one the baby had a HB but was measuring small, I then started spotting and after a few weeks I miscarried, it was horrible. I then had a very early miscarriage a few months later.
On the third try, after lots of research and friends recommendations I started taking 15g aspirin from ovulation every night and progesterone for the first 12 weeks. I got the aspirin over the counter and I private prescription for the progesterone as 2 losses doesn’t give me access to nhs investigations. The progesterone was expensive but I was desperate, and luckily after a few weeks I managed to speak to an nhs consultant and they agreed to prescribe the progesterone for the rest of the 12 weeks.
Both of these medications are taken on a ‘can’t hurt, might help’ basis so I’ll never know if they worked, but for me I strongly believe they did, especially the aspirin. The aspirin helps blood flow to the baby and therefore nutrients and oxygen, helping it develop. My theory was always that the first baby I miscarried was measuring small but had a HB because it wasn’t getting the nutrients it needed (but I’ll never know for sure).
I’m now 38 weeks with my third pregnancy and will continue to take the aspirin until I have baby next week via c section. I never thought it would happen for me but it looks like we might get our rainbow baby 🌈
This is just my experience but I would say you probably don’t need to go down the IVF route straight away, maybe try things like the aspirin first and see if it works as it may be all you need, as you seem to be able to get pregnant. But I’m not an expert ☺️
If you have any further questions feel free to ask - hope it works out for you xx
