The embryo is very well protected in there so I doubt it.
No
No, absolutely not. Not good for your health but won't cause a miscarriage or even a small baby.
No they can not.
It might in the first few weeks.
Yes you can have a miscarriage at 4 weeks I have hade a miscarriage at 2 weeks.
Take Tylenol instead
Typically, a five week miscarriage would cause bleeding like a period.
A medical abortion is only available up to 9 weeks.
Although I am not sure if you mean intentional or unintentional miscarriage, I know that there is a pill that is an "abortion pill" that does, indeed, cause a miscarriage.
i highly doubt that means miscarriage the doctors often say that when you hit your 3 months your risk of having a miscarriage is very low. the baby can just be shifting to a different position.
If you have a miscarriage at six weeks you probably won't see much more than blood clots as the embryo is still very small. See the link for a timeline and pictures.
The fetus is well protected so laying on your stomach can not hurt it.
i had that too, Im currently 6 weeks pregnant and don't have an ultrasound for another 2 weeks
