Every pregnancy is different. I know all three of mine were. Definitely contact your doctor about the cramping and bleeding. A small amount is probably normal, but if it is actually like a normal monthly with cramping -- I'd be concerned. I had that on my 2nd and 3rd pregnancy which ended up in miscarriages. That is so hard, but when I got pregnant for the 4th time -- i was able to carry it and had a little boy.
I was told the same, lay down put your feet up...... I did and the cramping just seemed to worsen. Hopefully this isn't the case for you and everything works out great. Just be careful.
I think a miscarriage is one of the most awful things women go through who wants to have children. Also try and reduce stress... I know that is alot easier said than done.... put your faith and this pregnancy into God's hands and I'm sure all will work out. Good luck.
