Hi N., The only thing I really have to say is that pregnancy isn't supposed to be comfortable, but it also is not supposed to be painful, my last girl I had started to give me what the docs call croch zingers, rather uncomfortable, but not painful, and I have had 4 c-sections, all I know is if it was me and my doc said I was fine, and I wasn't comfortable with the answer, I would insist on some more test to make sure for my piece of mind that everything is on the up and up, and if you are still not satisfied, get a second opinion, believe me from expierience with a doc during my first pregnancy, that they don't always take care of you the way that they should, my doc at that time neglected the complaints I had,(bad heartburn, so bad I had acids imn my mouth, chest pains so bad I could walk or take a breath, the list goes on)every time he would tell me I was fine, or you have to stay away from stress or take mylanta for the heartburn, his neglagence almost cost me my life and the life of my child, tuned out I had pre-eclampsia (I convolsed fron that), I also had toximia, and what is called H.E.L.L.P syndrom, which has sonthing to do with your blood cell clotting or not clotting, I was in poor health, what I'm saying is don't just take his/her word for it, give yourself piece of mind and insist more be done, you know yourself better than anyone else, I was only 18 when I expierienced that trama, kinda wish I knew then what I know now thing, don't hesitate to do what makes you feel more comfortable.
good luck and let me know how you are feeling.
