more painful cramps than usual should I be worried?

My husband and I have been trying to convince but unfortunately I started spotting yesterday and this morning my period started though I'm sad I'm more concerned by the insane cramps I'm having. I have no idea if I'm overreacting or if this a very early miscarriage? I didn't miss a period so I'm not sure what's going on. Any advice would help.
