Is there really something wrong or am I over reacting?

OK, most of you already know how I am when it comes to anything really. Those of you who don't really know me all that well I'll just say that I always think of the worst case scenarios and over react to everything that deals with life pretty much. That's just the way I am! LOL! When I was pregnant with my second baby (Aiden) I got these really bad pains on my right side down in my pelvic area. So the Dr of course did an ultrasound when I was 14 weeks along with him to see if I have cysts on my ovaries. It turned out that it was nothing but ligament pains and then the pains returned when I was about 8 months along and it wouldn't go away. My Dr informed me that it was just the baby putting alot of pressure down there and it wasn't going to go away until I delivered him. Which the pain did go away right after I delivered him. With this pregnancy the pain came back around 15 weeks. The only thing that is making me think that it's not ligament pains this time is that it is really consistent. I found out that the only way to make it go away is to stay really lazy all day long. That Intel's that I just sit on the couch, sleep, watch TV, read books, and get up to use the restroom and feed my kids. I did this on the weekend cause my weekdays are pretty busy with taking Mason to preschool and back and other errands that I need to do. So I have been researching online and I don't know what this pain is but it could just be the ligament pain again, cysts on my ovaries or something wrong with my appendix. I don't know so I'll just leave that to my Dr to decide and put my mind at ease. Tomorrow is my Dr appointment and I am definitely telling him all about this pain. Oh and I forgot to mention that the pain that I have it hurts like none other. Walking hurts, sitting up and down hurts, stretching out my legs, lifting stuff hurts and the list goes on. I am always tired and exhausted as it is too. I take naps everyday and go to bed by 10 pm every night. So if any of you have ever had this pain before please give me ideas about what to do that will help it go away. Let hope that I was really just over reacting and there is nothing wrong with me or the baby. Wish me luck!
