I'm 7 days before my aunt flow is supposed to arrive and yesterday the lower part of my tummy the abdomen started feeling like I pulled or stretched a muscle and is sore when I walk or move the wrong way, now I'm dealing with this still and wanted to know what anyone had to say... please all the feed back is great
