Abdominal pain and dizzy spells

Hello.
I would like to start by saying I am one who does not normally get sick often and this does not happen to me a lot.
2 weeks ago on the 4th of July about 5pm I got extremely painful cramps all through my stomach, they were very painful and I could not pin point exactly where, they didn't stay on one side or the other it was all over my stomach. After a little while of the pains then the nausea came and sometime into the night I did vomit and that is when the pains started to lighten up. The next 2 days I still had mild pains but I was able to go about my daily activities. Now July 19 around 10 pm I got up normally it wasn't getting up too fast dizzy it was different for me. I got up and nearly fell over I grabbed hold of something the room was just spinning so bad. But this didn't stop til the next evening around 4pm the spinnin stopped but I still have mild lightheadedness/mild dizziness. I am 30 yr old female and this stuff isnt normal for me to experience. I have done the getting up too fast and getting dizzy but this was so much worse than that. I still have about a month to wait before my husband's insurance will start so that I can go to a doctor, I was just hoping I could find some help on here. And I've never had any issues before with sugar levels, or blood pressure I read that's one of many things it could have been and I know it's posible Im just letting you know it's never been a problem before. Thank you very much
