You need to consult your physician or better yet your GYN Specialist about this especially if this is happening all the time.
You can also try using a warm heating pad across your lower abdomen.
Hi Tamar21, does this happen every month? I would get it checked out, it could be just a bad month. It could be something more serious if it happens a lot. I would make an appointment and tell the gyn the problem, they can do an exam and run some tests to figure out what the issue may be.
