Sharp Random Pelvic Pain

I'm having random sharp pain in my pelvic area. I've felt them on both sides but mostly on my right and more often then before. I've felt these pains long before I got pregnant (4.5wks) and always thought maybe they're hernias. I feel them when I sometimes stretch in bed, going to the bathroom, and just now when I went to stand up. They're so sporadic and short lived I've never sought medical treatment.. I had two hernias when I was 5yo and I don't remember how they felt like.. But now that I'm pregnant I'm worried, no, terrified it might be a ectopic or tubal pregnancy... And if it is a hernia.. How will that affect this pregnancy? Has anyone had similar experience? Thanks.
