This is my first period since being off the pills. I'm so crampy. ( I haven't even started bleeding yet)If I'm sitting it's okay but when I stand up it feel like someone is squeeZing my lower abdomen. It goes away in a minute after standing. I'm almost 30 and I've always had painful periods. I'm probably over reacting but I'm just hoping someone else has felt my pain. Literally. My lower back hurts like it normally does so I knows it's coming soon. Just the spasms that are worrying me. Also I'm a little lightheaded when I stand up I get a head rush just a general blah feeling all day. I'm hoping this is just the mother of all PMS and not anything worse
