Yes, you should see your doctor. The lining of your uterus will probably need to be cleaned by a surgeon. You could get infection and even blood poisoning if you do not seek medical attention.
To check your health and ensure there have been no adverse side effects of course.
Typically, a five week miscarriage would cause bleeding like a period.
nothing unless you want to change it
you usually wont have a miscarriage after your first trimester (third month) after that you would just have a still born baby.
there isn't one I think most people would say they had a miscarriage before about 16 weeks and that they had lost the baby after that.
A heavy painful period with clots.
For that to happen to a healthy pregnancy it had to be a really bad fall and the miscarriage would not likely be the only injury. The fetus is very well protected in the uterus.
since you have had a prior miscarriage I would have it checked out
Yes, it should do. At 6 weeks, it won't have got much bigger. I would expect it would take about 6 weeks for it to get back to its normal size again.
So many times the zygote has defective chromosomes. It is possible that you get pregnancy almost every month after the marriage and the defective zygote goes out with your menses only. The normal or near normal pregnancy is preserved by nature. So you may not notice miscarriage of only about three weeks. It is not necessary to know the same. That is expensive and useless.
I would say only 3-4 weeks.
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
