Ohh I am in the same situation, I am concern since I had other two miscarriages and this is my first pregnancy, but I have read all day, that is normal, I have my appointment with my OB this friday, so I will ask her and I 'll let you know.
This is my 5th pregnancy and I'm cramping all the time. I think majority of it is I don't drink near enough water like I should. As long as your not bleeding its prob just your uterus stretching and could be from not drinking enough water.
This is my 3rd pregnancy I'm currently 17 weeks with a little boy ..I have a 6 year old daughter..with my daughter I had no cramping what's so ever ..with this pregnancy I've had cramping and pain from day one ..at times I thought I was gonna miscarry I was cramping so bad ..so far everything looks normal and healthy ..about 5 years ago I had a missed miscarriage at 14 weeks I had no cramping an slight spotting I had to get a dnc to remove everything ..hang in there I know its scary but more than likely your uterous an ligaments are stretching ..I still get cramps and weird pain but my Dr reassures me its just the baby getting bigger ..also when you start cramping lay down for a little bit and get some rest drink lots of water and most importantly don't stress ..Congrats ..
