I have never posted before. I do have a question if anyone can help me. I am about 4 days late for my period. For the past 5 days I have been having really bad cramps and have to run to the bathroom A LOT!!! I took a home pregnancy test and it came out negative. I am wondering if I have a bladder infection, although I am not sure how to tell the difference between early pregnancy signs and bladder infection from what I have found and read. Any suggestions?
