they say that the baby is most active between 24-28 weeks that might explain why the baby isn't as active.
Also, they baby might be positioned on your bladder causing you to have frequent urination.
Some women experience braxton hicks contractions throughout there whole pregnancy while some women never experience them, so that doesnt always mean labor.
You could be experiences round ligament pain because the baby could be having a growth spurt or something of the sort. If your experiencing alot of sharp pains or cramping maybe try drinking some more water.. dehydration can cause cramps or sharp pains.
Hope this helped alittle bit.
Good Luck and keep me updated
