PLEASE READ BELOW!

I dont want to go to the hospital if I dont need to because I do not have insurance YET so please give me some NICE helpful advice on what you think..?
First off, I am 10 weeks pregnant.
About 10 minutes ago I started getting sharp lower abdomin pains like almost felt like what "contractions" would feel like, I'm guessing. But it wasn't THAT bad. They came and went away about every 20 seconds and now its been over 10 minutes and it hasn't come back. I am getting NO spotting.
I keep checking. Do you think it is just my uterus streching or could it be possible miscariage about to happen???
