There could be numerous things that you're going through. The cramping could be a sign that your period is about to start; have you been under a lot of stress lately? The sure sign is to get a pregnancy test. Of course, EPT is the best but if you have a Walmart, Equate's version is just as accurate (and it's cheaper). What type of cramping do you have? Is it sharp or dull? Sharp cramping could be a problem, especially if you're pregnant. Get a test done, ASAP and then go to the doctor and let them know about your cramping.
