So my period was due today and didn't show up yet...I have no symptoms of it coming. Usually my boobs hurt real bad I have the worst cramps in the world and I'm starving all the time. However my boobs were aching all month long and just stopped a few days ago. I keep feeling like a pulse feeling in my stomach right under my belly button or on my right side. I keep getting naucious but never throw up and after I eat i always feel full but I'm still hungry. I just don't know what's going on
