I'm 15 weeks and since yesterday morning have had pains in my stomach on and off. They seem mainly to be on my left hand side, quite low down and feel a bit like trapped wind. It's nothing like period pain. I thought it was wind but without being too graphic, nothing has shifted it yet. It's not a constant pain and does seem to be affected by going to the loo (was there every 1/2 hour yesterday but don't think it's a bladder infection as I did genuinely go- but felt it then)- my lower back is also quite painful. It got quite bad last night but eased a bit by this morning, athough I'm still aware of it. Does anyone know if this is likely to be some kind of muscle strain or should I get it checked out? Im not sure if it could be a stomach bug as I've had diarrheoa (SP!) and have felt a bit under the weather. Have contacted my GP but they can't fit me in and to be honest don't know if I need to go! If I wasn't pregnant I probably wouldn't worry about this too much but all of dh's advice and reassurance haven't helped so far. Sorry to go on but i'm a real worrier! Does anybody have any advice on what it could be?
