Prenatal Care is very accurate and doctors and various tests as well as fetal heart pulse are consistently checked...it is very unlikely that if indeed there was a miscarriage at twelve weeks that it would not be dectected on visits. Dr.'s are pretty accurate,but the first time I was pg,the dr. could not get a heartbeat. They told me you usually can not hear the heartbeat till twelve weeks. So they told me I may have miscalculated how far along I was. I knew I was right and started spotting and decided to see another dr. . Finally after seeing this dr., I found out that the baby's heart had stopped beeting at 11wks.and I was almost 17wks along. The dr. did a d&c. My case may have been very rare, not to say that it happens to everyone, but there is a small chance that it could happen. Best of luck to you!!!
Most statistics say that up to 12 weeks, the chance of having a miscarriage is up to 20%, or higher in people who have had miscarriages in the past or are at a high risk of having a miscarriage. Lifestyle factors such as smoking, drinking, or using recreational drugs can also increase the chance of having a miscarriage. However, after 12 weeks, the chances drop to less than 5%, if your doctor has found a healthy heartbeat.
That"s a new one on me- Atoms can split- with usuallly humungous destructive effect- but I have never heard of a radiation miscarriage, though I am sure it can happen. It has been found crewmen who serve too long in the reactor compartments on Atomic subs- and these operate ( buttoned-up) for 90 day patrols) have shown symptoms of sterility. Naturally there are limits on how much sub duty the crewman can serve- and to some extent the problem can be ameliorated by remote controls- generally placing the reactor room (Off limits) in normal duty hours. This is another argument against Waves on submarines!
Only few studies have investigated wheatear use of clarithromycin during pregnancy is associated with miscarriage. Some animal studies have shown that rabbits and monkeys have increased rates of miscarriage when being exposed to clarithromycin during pregnancy (Biaxin product information). Adrienne Einarson and her colleagues observed in 1998 that women exposed to clarithromycin during pregnancy had a doubling in the risk of having a miscarriage. Recently Jon Andersen and colleagues found a 50 % increase of miscarriage in women exposed to clarithromycin in early pregnancy both compared to untreated and compared to women exposed to antibiotics used in same conditions. The results indicate an association between clarithromycin and miscarriage.
According to a 2008 study published in the journal, Obstetrics & Gynecology, miscarriage risk falls rapidly with advancing gestation. The researchers studied miscarriage rates of 697 women and found that the risk of miscarriage at 6 weeks gestation was 9.4%. At 7 weeks gestation, the risk of miscarriage fell to 4.2%, and at 8 weeks of gestation, it fell to 1.5%. The overall miscarriage rate for this group of women was 1.6% (11 of the 697 women miscarried at some point during their pregnancies). This study involved women who did not have any symptoms of miscarriage when they were first enrolled in the study, and where evidence of fetal heartbeat was seen via ultrasound during their first prenatal visit (the first visit took place between week 6 and week 11 gestation). So, if you have seen a fetal heartbeat on the ultrasound, and if you are not experiencing any symptoms of a miscarriage (i.e. heavy cramping, bleeding), then your risk of miscarriage is likely to be similar to the women in this study.
Having a miscarriage will not cause endometriosis. However, women diagnosed with endometriosis have been found to have a higher rate of miscarriage than others. Endometriosis is a leading cause of infertility. Please know that many women with endo do have healthy babies. (I am one of them!) Please join the Endometriosis Association at endometriosisassn.org and check out the book, Endometriosis, by Mary Lou Ballweg. Good luck!
it does not always mean miscarriage as some women have a bleed during pregnancy but it could also indicate a missed miscarriage which is where the baby has died for what ever reason and you haven't lost it i would suggest that you go to your g.p's and ask for an urgent scan to check if the baby has a heart beat. i had a missed miscarriage at 14 weeks pregnant my body still thought i was pregnant but the baby had died at 9 weeks and 2 days. hope this helps
