![]() ![]() Women whose last induced abortion occurred 12-24 months before the current pregnancy with no pregnancy in between the induced abortion and the current pregnancy faced an increased risk of miscarriage (odds ratio = 2.28). Second trimester abortions were associated with an increased risk of first miscarriage (odds ratio = 4.63). The researchers found the same risk when they adjusted for vaginal infection. When comparing women who had had a previous pregnancy with primigravidae (first pregnancy), women whose 1 previous pregnancy ended in induced abortion, those whose 2 previous pregnancies ended in induced abortion, and those who had at least 1 induced abortion in their 3 or more previous pregnancies faced an increased risk of miscarriage (odds ratio = 1.41, 4.43, and 1.35, respectively). Induced abortion increases the risk of miscarriage 128% for up to 2 years The excess risk of miscarriage was observed with both preovulatory and postovulatory conceptions. The adjusted relative risk of miscarriage among women with non-optimally timed conceptions and a history of pregnancy loss was 2.35. This association was not observed among women with no history of miscarriage. ![]() However, among women who had experienced a miscarriage in a prior pregnancy, the rate of miscarriage in the index pregnancy was significantly higher with non-optimally timed conceptions (22.6%) as compared with optimally timed conceptions (7.3%). ![]() Instead, the risk seems to increase with number of previous miscarriages and deliveries, and possibly the risk is highest in the youngest and oldest women.Ĭonceiving on the day of, or just before ovulation, halves miscarriage riskĬonceptions on days - 1 or 0 with respect to the natural family planning estimated day of ovulation were considered to be "optimally timed," and all other conceptions were considered as "non-optimally timed." The miscarriage rate was similar for optimally timed conceptions (9.1%) and non-optimally timed conceptions (10.9%). NT thickness up to 3 mm does not seem to affect the risk of miscarriage in such pregnancies. CONCLUSION: In singleton pregnancies with low risk of Down syndrome at 12-14 weeks, the spontaneous fetal loss rate before 25 weeks is likely to be around 0.5%. Excluding women with any previous miscarriage and adjusting for parity, we found a U-shaped relationship between maternal age and miscarriage. After having controlled for maternal age, we found the number of previous deliveries and miscarriages to independently predict miscarriage: odds ratio for each previous delivery 1.48 odds ratio for each previous miscarriage 1.34. The study population comprised 14,278 singleton pregnancies with a low risk of Down syndrome. OBJECTIVE: To estimate the risk of second-trimester miscarriage in women with low risk of carrying a fetus with chromosomal abnormality. In my experience there isn’t an easy solution, just feel the all those shitty feelings, talk about it with people you trust, and work out a game plan if the anxiety sneaks back in during your next pregnancy.Second trimester miscarriage risk is 0.5% higher with previous delivery or miscarriage Definitely re-test if it will assuage your fears or for that matter, do whatever will make you feel better! But honestly it’s just scary trying to get pregnant after you have your hopes dashed. In terms of your apprehension with the remaining embryos, I think those feelings are the unfortunate result of a miscarriage (of any sort). I’m really sorry though, I know it feels extra crappy when you think you’ve accounted for all the risks, paid a ton of extra money, and waited for the results, just to find out you were still on the wrong side of the statistics. The explanations are always: “bad luck, it’s only a small percentage, it’s not 100% accurate, blah, blah.” I’m sure it helps in some scenarios, but we opted not to do it on our next attempt and we’ve had success (so far!). The more I hear about PGT, it seems it isn’t as reliable as they say it is when it’s getting sold to us. ![]() Haven’t had that exact situation but I MC’d with a PGT embryo last year (2019). ![]()
