I had my first real cycle after depo I got my period jan 31st I'm not sure when I ovulated or anything like that but I'm on cycle day 29. All day today I've had some pretty heavy cramps and a "heavy" feeling in my uterus / abdomen. It's so weird. Last period I had I didn't start cramping until I had started my period and so far I haven't had any blood at all just like school glue cm. Has anyone felt like this? It's got me a little concerned
