IUD confusion

Hey guys I recently got an iud dec 14th to be exact. I have the hormonal iud and I had a regular period last month but I’m not sure if I’m having a period this month. I have some spotting and the pms symptoms but that’s it. Also there’s a very little chance of any that I’m actually pregnant. I was wondering if this is normal with the iud? I have been prone to irregular periods in the past
