If the sharp pains start coming on a regular basis, you could be going into labor. I would call your doctor and at least let him know what is going on with you; especially with the weekend fast approaching. If you try to lay down and the pains keep coming, chances are you could be in labor. You can start having these pains even a few days prior to on set of actual labor so I would definitely monitor them closely. Take care and good luck. Have a happy and safe delivery.
The sharp pains are probably contractions.
I'm no doctor, but if the pain is that bad go to the ER NOW!!!!! A friend of mine lost her baby at 8 months...she also had sharp pains. Not trying to scare you, but you need to go to the doctors.
I'm 37 weeks almost 38 and I know that I too feel horrible on a daily basis and that I just dont feel like eating and half the time I feel like I am going to throw up as well. My doctor said that it is completely normal to feel horrible at the end of a pregnancy and not wanting to eat is because we have a lot going on not to mention your little one is cramping your stomach making it feel full before you really get anything in it. There isn't really anything you can do unfortunently. Maybe try some tums but nothing works for me other than water and sleep.
