Period pains 4 to 5 days before period

Hi! I had the coil taken out at the end of November. My periods have been regular and the same every month as I've been logging everything. We are due to start trying to conceive later in the year. So we are using condoms. I'm due on Thursday/Friday and I'm getting bad period cramps today (Sunday) I've never had period cramps before my period. Is this normal? Is my cycle only now sorting itself out from the coil do you think? It's just very unusual for me! Thanks.
