Eptopic or no?


I just did some reading and now I'm worried like crazy.

I've been having pains in my lower abdomen now on my right side there's a knot that showed up when I tried to get up to fast off the toilet. It's hurting really bad I'm constipated (but that's a common preg symptom) I've also been getting dizzy and feeling like I'm going to pass out. The only thing I haven't done is bleed. The pain goes into my shoulder and neck too. What do yall think? Am I just stressing myself for no reason or should I be worried?
