Pregnant my stomach has been cramping and I've been trowing up all morning? (TMI Question)?

I'm 9 weeks prego and I'm having extreme morning sickness as well as Bowel problems (TMI ALERT> but I haven't had a normal bowel movement in over a week called the Dr Several Times Trying Milk of Magnesium, Suppository, Colace....fiber...water ....etc. And my when I do use the bathroom it's very hard to p and extremely painfull..I end up throwing up after I use the bathroom cause of the pain) But I had an episode last night again with the bowel problem and I never started to feel better later that night...I felt sick to my stomach and having sharp pains every now and then..So I ate a bowel of cereal before bed and some jello...I woke up throughout the night feeling extremely sick...as well as this morning..So I made sliced apples and eggos for my kids and I for breakfest....And still feeling nautious I started throwing up all of a sudden and I haven't been able to stop for over 30 mins now (It's in waves of every 5 to 8 minutes) Could I just have stomach bug or could this be a G.I. Track Problem?? I have a Doctors apt tomw for my first sonogram but I'm not sure what I should eat again since It seems like every thing I eat or drink something It comes back up
