Ectopic pregnancy

Anyone have experience with an ectopic pregnancy? I had a miscarriage in August at 10 weeks and am currently 7 weeks 2 days. I've been having a sharp pain on and off on my right side the last few days and I'm concerned it might be an ectopic. I dont remember having these sort of pains the first time around. The pains aren't debilitating but at times they are sharp and uncomfortable. I'm going in for my first OB appointment on Friday but am concerned I should be seen before that in case it's ectopic. I don't have any bleeding so far and while I've been nauseous in the mornings I don't have any other symptoms during the time I feel the pains. Thanks for any advice you might have!
