Am i worrying too much??

I had a bleed the other day, and since there has been no bleeding and the dr is satisfied that everythings ok, but...I feel like something is not quite right, ethans h/b is fine and he is moving ok, its hard to explain but its just a feeling that wont go.

I have been getting some pains, really sharp that last about a minute, really low down in my pelvis area and my crotch too, that are on and off all day, when i mentioned this to the dr he really didnt say anything except, i need to rest and slow down (not that i've been doing much any way!!) Also i have had a constant ache in my lower back. Im getting b/h contractions quite often but they seem to be less intense than before. I have also seemed to have lost my belly a bit, strange way to put it but I have my belly button back!! 2 days ago it was flat you couldnt tell i had a belly button, now i have an inny again and my belly is small again.

Is all this normal for this stage of pregnancy? I know im probably being paranoid but i just wanted to be sure.

TIA (sorry if i sound like a hypochondriac. sp??)

Hi Tears of Joy
Everything sounds fine to me.
The reason you have lost your belly is because you baby has moved down into your pelvis. You probably feel that you can breathe more easier than before.
The pain you are feeling is caused by a hormone called relaxin which causes all your joints and ligaments to relax. You have a joint in the middle of your pubic bone and when this becomes loose it causes a sharp pain.
