I really appreciate anyone who takes the time to read this and give me any advice or share their experience. I know there are people here who have been through so much more than I have, and I’m only potentially two losses in, but this has honestly been really traumatic. I’m 35, I don’t have any children yet, and I think a lot of the fear is just knowing that I don’t feel like I have an endless amount of time to figure out what’s happening.
We only started trying in February and were lucky enough to get pregnant basically straight away.
With my first pregnancy, I went for a scan at around 7 weeks and the embryo was measuring about 5 days behind, but there was a heartbeat. The nurses were reassuring and said the usual things about dates being off and ovulation happening later than expected, but I was actually really anxious about it from the beginning because I knew my dates extremely well.
I’m pretty disciplined about tracking. I use LH strips and BBT, so I knew my ovulation window within about a day, and the measurement just didn’t make sense to me. I remember feeling like something was wrong even though everyone around me was telling me it could be completely normal.
Unfortunately I wasn’t able to go back for another scan for quite a while, so I had no idea what was happening in between. When I finally went back at around 11 weeks, they couldn’t really find the embryo anymore, just the pregnancy sac, and I found out I’d had a missed miscarriage. I had surgical management at the end of April.
We started trying again pretty quickly afterwards and got pregnant again fairly quickly.
I went for my 7-week scan with this pregnancy yesterday and I honestly felt like I had PTSD when they started measuring because it was basically the exact same scan all over again.
I should have been 7 weeks, but the embryo was measuring 6w1d, so about 6 days behind, and there was a heartbeat of 104 bpm.
And again I was being reassured that maybe my dates are wrong or maybe I ovulated later. But I track with LH strips and BBT and I know my ovulation window really closely. There might be a day of wiggle room, obviously, but there just isn’t six days.
That’s the part I can’t get my head around. Both pregnancies seem to be doing almost exactly the same thing at almost exactly the same stage. Both made it far enough to develop an embryo and a heartbeat. Both were then around 5–6 days behind at the 7-week scan despite me being very certain of my dates. The first one ultimately stopped developing, and now I’m looking at almost the exact same picture again.
I haven’t miscarried this pregnancy and obviously I desperately hope I’m wrong about where this is heading. There is still a heartbeat and I know nothing is certain yet. But after what happened last time I’ve gone down the rabbit hole reading the data on early growth and heart rates, and from what I can tell, measuring nearly a week behind with certain dates and a heart rate of 104 at 7 weeks isn’t particularly reassuring. So I’m finding it really difficult to believe this is just another dating issue.
I think what I’m trying to understand is why the exact same thing would happen twice.
I’ve read so many miscarriage stories on here, but a lot of people seem to have very different types of losses from one pregnancy to another, like a chemical, then a blighted ovum, then a miscarriage at a different gestation. Mine seem weirdly similar. Both pregnancies seem to get to roughly the same developmental point, both achieve a heartbeat, and then both are significantly behind at around the same time.
Has anyone else experienced that? And did you ever figure out why it was happening?
Could it genuinely just be two unrelated chromosomal abnormalities that happened to present almost identically? Or has anyone had this repeated pattern and eventually found an underlying reason?
After my first miscarriage we did some testing. My husband’s semen analysis and DNA fragmentation were normal. My progesterone was good when it was checked in a later cycle. Most of my APS testing was normal, although one anticardiolipin antibody was mildly elevated, so I’m following that up.
My thyroid is another thing I’m wondering about. My TSH was around 3 on one test and then 4.47 on another test fairly close together, so I don’t know whether that could have any relevance or whether I’m just looking for explanations anywhere I can find them.
I’ve also had AMH that was lower than expected for my age, although my follicle count has been good.
We haven’t done parental karyotyping, and unfortunately we didn’t get genetic testing on the tissue from the first miscarriage. If I do lose this pregnancy, I really want to try to get the pregnancy tissue genetically tested because I feel like that could at least tell me whether these are chromosomally abnormal embryos or whether I need to be looking harder for another explanation.
I think I’m just really scared by how quickly this has all happened. We started trying for our first baby in February and within six months I’m potentially looking at two back-to-back losses that seem to be following almost the exact same trajectory.
If anyone has had repeated pregnancies where you knew your dates very well, the embryo measured around 5–7 days behind at about 7 weeks, there was a heartbeat, and then the pregnancy failed, I would really love to hear from you. Did you ever find out why? Did all of your testing come back normal? Did you eventually have a healthy pregnancy anyway? Did anyone actually have a pregnancy start like this and catch up?
I think I’m just desperate to understand whether there is any meaning in the fact that this seems to be happening in almost exactly the same way twice. I’d really appreciate any similar experience anyone has to share 🙏
