So I've been having some light cramps occasionally for about a week and read that that's normal for the first trimester. But last night I started having more intense cramps on my right side that lasted about an hour. (No bleeding or spotting).I was already in the er for something unrelated and asked the dr. if that was normal he said it was just a part of pregnancy. However I read it could mean ectopic pregnancy. My question is should I be worried? And dies ectopic pregnancy come with any more symptoms?
