When i woke up, while still laying down everytime i moved my head i got really dizzy and stomach was knotted?

a few days ago my lower abdomin had a really hard knotted feeling inside, bloated enough that it looked like i was pregnant, and i couldnt even suck in. it would hurt everytime i coughed, sneezed, or went to the bathroom. everytime i would get up from sitting down i would get light headed, the feeling you get when you get up too fast but it would happen everytime i got up. and when i would lay down i would get a dizzy feeling in my head. i am a 17 yr old female. thanks for anyone who can help me
