For the Last couple of months I haven't felt like my normal self. I've missed two periods. Im uncomfortable anyway I sit or lay down,there is always a tingling feeling in my abdomen and sometimes it feels like something's moving but I'm not sure and to top it off my breast are really sore. I took a pregnancy test and it came back negative, now what?

Now it would be time to visit your doctor for an exam to try and determine a cause.

Maybe you just have an hormonal imbalance, visit your doctor as soon as possible... birth control can help with this if that is the case
