Help!!!

Chloe
Hello my name's Chloe I had some problems the last couple of weeks with pain and period like cramps and thought I had a urine infection I went to the doctors 2 days ago to find out I'm pregnant I've had this pain in the lower right side of my belly and the top of my right leg I had my first bloods yesterday and they said to go back for a comparison on sunday to see if the hcg level doubles but said that the first blood was about 1,120 (don't remember exactly) so that not too bad but I can't stop being worried and was wondering what else the pain there could be? (Really hoping it's not ectopic)
