About two weeks ago i was feeling nauseous, and had swelling in my ankles, and slightly dizzy, i thought that i may have been pregnant but not sure, but now i have had my period which is very heavy, it has always been heavy. but i had heavy cramps and i have not had cramps in years, i have heavy periods but no cramps, could this have been an ecoptic pregnancy or just the fact that i have anemia and my hemoglobin levels were low
