FTM

I honestly can't tell if I'm cramping or having these practice contractions. My normal cramps, when I'm on my period, feels like I'm being torn from the inside out. I've been getting some sharp pains but I can't tell what it is! Does anyone know the difference? Thanks in advance to those who answer.
