Now I need to make an appointment with my doc. Anyone any experience?

hmm you need to go see the doctor fast and stop trying to look up things online. If you have pain in your tummy and its getting big then yes you need to go there fast , I would suggest go in to emergency or some place where you can get check immediately.
