So probably an overreaction but...

So this is my first pregnancy and I'm probably just freaking out but for the last 6 hours I have had the worst cramps and I think Braxton hicks contractions. 
The pain was so bad I was on all fours trying to ease it. There was definitely more than I think 10 'contractions' in an hour. 
I had a shower and took some paracetamol and tried to eat but I vomited so I tried to go to sleep. 
Woke up two hours later with radiating back pain, cramping and discomfort. 
I'm worried because I was born at 28 weeks so I'm worried this baby is going to be premature. 
Sorry for the long post. Any advice would be greatly appreciated. I just don't want to call the doctor and they think I'm being silly :(
