I know it's scary, but I wouldn't worry. I remember heading into urgent care during my first pregnancy at about 5 weeks with similar sharp pains. It was very painful and I was scared. I was told it was round ligament pain as things begin to loosen, stretch and move. It improved after a few days, but every so often I would still get sharp catching pain in the area. It still hurt but the pain was a lot easier to deal with after I knew what it was. Good luck.
