Pains - could it be a miscarriage?

I am 9 weeks 6 days and have been experiencing extreme pain in my pelvic area tonight. The sharp pains last about 5 seconds and dissappear and return every minute or so. I have been throwing up due to the pain and not sure if this could be a miscarriage or if this is just part of the ride. I live rural so I dont have the option of seing a doctor until Monday (currently friday night here) anyone have any advice? TIA
