Similar to previous posters: I had two consecutive miscarriages in 2019. One at 8 weeks, one at 11 weeks. I had an ERPC for the first and was going to opt for medical management for the second, but (thankfully) avoided it as my body miscarried whilst I awaited my appointment to receive the medication.
Mentally, I wasn't in a great place and felt I needed to seek answers, or at least, have a plan in place. I went private and had consultations and was going to have a round of tests. My partner had a sperm analysis which was all clear. Before my tests could commence, I was pregnant again - but the clinic were absolutely brilliant. I got prescriptions for steroid tablets, progesterone, aspirin and blood thinning injections. My daughter was born in September 2020. Cost around 4k for medications, tests, consultant fee and numerous scans. I'm in London, if that helps.
I'm pregnant now and decided to see what would happen without intervention. All seemed fine but at 9 weeks I started spotting which is how my two previous miscarriages started, so I thought I was in for another. Was scanned in the EPU and baby was fine, no reason for bleeding found. I pressed for a progesterone prescription and got it, because NICE guidelines changed in November 2021, and women with previous miscarriages and bleeding will not be prescribed 400mg twice daily without the need to see someone privately. Your GP can do the same for you, just go armed with the NICE guidelines if necessary and applicable. I was already taking baby aspiring (150mg daily every evening) as that's what I had done in my other successful pregnancy.
I'm now 23 weeks and all seems ok at the moment, hoping it stays this way.
I do think it's a personal choice if you want to opt for tests privately or not, there is a cost involved certainly, and it's not cheap. However I've read many threads on here and seen positive outcomes for lots of women who decided to opt for private support.
Good luck and I'm sorry for your losses. It's so hard!
