Withdrawal bleeding or period?

Hey guys, so I’m not sure what’s going on but would love some help.

I got my IUD taken out on Dec. 28, it was during my “period”. My periods on the IUD were light spotting and lasted up to a month. After getting it removed I had one tiny little spot when I went to the bathroom and nothing else till the 30th. I started (I think) my period? I cramped and started bleeding with some small cloths. It’s not heavy or anything. I’m not sure if it’s withdrawal or my actual period coming on? It stopped last night and started up again around lunch.

I’m hoping that it’s my period to get rid of all the chemicals and lining for a pregnancy.

If you have any advice, I’d love to know. TIA 😊
