I was suppose to get my depo shot the beginning of this month and I missed it. Still haven't gotten my period but my ankles are swollen after working for only two hours (usually work 8-10 and never had them do that) abdominal pains, fatigue, and lower back pains/cramps. Also really bad gas. Sometimes when I eat I want it at first but then makes me feel sick. I'm not sure what it is... Does anyone know if it's period symptoms or pregnancy symptoms? My pregnant friend thinks I'm pregnant. I took a test but it was negative
