Your body does not learn to have miscarriages and please don’t repeat that again. It’s damaging and incorrect, and to be quite honest I don’t know why you would say something like that.
There is always a medical reason even though science might not know what it is yet. The advances that have been made in the last 40 years in regard to understanding the causes of miscarriage have been akin to watching the Big Bang - and yet it’s just the tip of the iceberg.
OP.
The odds of having a single miscarriage is 1 in 5. It’s thought about half of these are due to chromosome issues.
Of the women that have had 1 miscarriage, about 20% of these will have a second, Again, many of these will be down to chromosome issues. Lightning can strike twice. Having 2 miscarriages doesn’t mean there’s an underlying cause. It might mean there is though which is why many countries (not the UK unless you are 35+) will test after 2. Even after 2 miscarriages though, only 25% of women will have a third. That sounds like a lot but it also means 75% of women will go on to have a successful pregnancy.
Only 1% of women will have 3 or more miscarriages. This is when an underlying cause is more likely. 40% of women who have 3 miscarriages will have another (I am in this group).
I was referred to the recurrent miscarriage clinic after 3 miscarriages. It should have been after 2 as I was 37 but they missed me (although they saw me very quickly when I questioned it after my third). I waited for testing and results because even though my biological clock was ticking, my biological clock was ticking and I didn’t want to lose time to another loss if that makes sense. I turned out to have a clotting disorder (APS) that can’t be tested for when pregnant, which is one reason they ask you to wait, and my next pregnancy was successful. It meant that without treatment my odds of miscarriage were about 82%. With treatment the odds of success are about 80%. The diagnosis was doubly important because APS means I’m at risk of clots which could cause stroke or heart attack, so I now take a daily aspirin as a precaution.
I was pregnant a month after diagnosis and baby arrived exactly a year to the day after my first appointment at the clinic. I had another miscarriage following this but to be fair I was in my 40s at this point. My OB added progesterone and the next pregnancy was successful. So you might need help but even so for every 4 women who go in to have a further miscarriage, 6 women have a successful pregnancy. Got my fingers crossed for you.
I asked at my first appointment about what would happen if I got pregnant between tests and they’ve told me they would monitor me, probably prescribe aspirin and heparin as a precaution (because so many issues are down to clotting) and scan every 2 weeks in the first trimester. You remain under the clinic for all future pregnancies. I moved house during my last pregnancy and was picked up right away by the local clinic, just gave them a call.
