No, the trip did not cause the miscarriage. Oftentimes a miscarriage is caused by chromosomal problems that do not allow viability. Sometimes there is no reason for a miscarriage and no one knows why it happened.
Please be assured that nothing you did (unless it was very traumatic like a car accident) caused your miscarriage.View Thread
It takes 6-10 days for a fertilized egg to implant and another several days for there to be enough of the pregnancy hormone to produce symptoms. If it hasn't even been a week, it's way too early for symptoms. With both my pregnancies, the earliest I started having symptoms was 5 1/2 weeks along.View Thread
Regarding your poll, yes, you can be pregnant and have no symptoms. A regular poster was pregnant with twins and didn't have any symptoms.
As for why you don't have any symptoms it could be because you're not pregnant. Home tests are pretty accurate and since you've taken two and they've both been negative chances are good you're not pregnant. You will need to work with your doctor to figure out why you haven't had your period for three months.View Thread
False positives are pretty rare and two are pretty much unheard of. Blood tests are usually pretty accurate but even then there are times when those are wrong. If you got a positive, chances are you're pregnant.View Thread
