I'm currently twiddling my thumbs waiting for aunt flo. She's 6 days late. I've never been this late before. Taken two hpt (strips) and both negative. Since July my periods have been temperamental. In September I had two periods a week apart - just weird! Also for the last few days my stomach muscles have been tensing and twinging and I've done nothing different like exercising. Anybody had anything similar happen to them? Any light shedding (ha!) would be appreciated
