I have a heavy feeling in my abdomen below my belly button. It started today and is stronger tonight. I was supposed to start my period 4 days ago, but all I had was a little bit of spotting (it was brown in color) that only lasted an hour.
I have had cramps off and on for over a week, thinking I was going to get my period but it never really came. I took an HPT the night my period was supposed to start, but it was negative.
What could this heavy feeling mean?
