At six weeks pregnant the baby is around 10mm big. If you are showing it is probably a distention of your bowel, more than the baby pushing your belly out. I would say that you are not "showing" in the true sense, but it is possible that your belly is sticking out a bit. You are more likely to begin showing at around 10 weeks pregnant.
No, at six weeks the uterus is only about the size of a walnut and it not yet large enpugh to comeout of the pelvis. Most women are visibly pregnant naked from about 14-15 weeks and a couple of weeks after that they look pregnant clothed. No, but you may be bloated from your intestines slowing way down and you may have put on some water weight.
no its impossible
The statement that you are six weeks pregnant means that you have been pregnant for six weeks, hence, you conceived six weeks ago. Bear in mind that these are estimates, they are not necessarily accurate down to the exact day. But they are reasonably good estimates.
That can being as early as six weeks -- sometimes early if you have been pregnant in the past. If the cramping you feel is accompanied by blood or is excrutiating, contact your OBs office at once as you could be having a miscarriage.
Yes
Six weeks into a pregnancy the uterus is still down behind the pubic symphisis, in the pelvis, so a jump on the tummy wouldn't be a direct hit. However, if you have any symptoms such as bleeding, or your pregnancy symptoms being gone, I would go to the doctor.
We average four weeks to make a month. That would make you six and half months pregnant.
At 34 weeks, the fetus is roughly 18inches (45cm) from top to toe
Yes it's normal
At six weeks your uterus is still tucked behind your pubic bone, it isn't large enough to be felt until after 12 weeks. Right now your uterus is about 3" long and 2" wide, this is more than big enough to hold your little micro baby who measures (CRM) just 2mm to 5 mm from crown (head) to rump (butt). Babies often are measured from the crown to rump rather than from head to toe because they spend most of the pregnancy curled up, but also because this early, their legs and arms are just buds.
