Ttc after 4 years of IUD removal

Hello ladies!!

Me and fiancé recently made the decision to remove my iud in early November. I did get my period early December, so I thought. But I was wondering if anyone has had trouble ttc after having an IUD for an extended period of time.

I have been cramp-y for the last full week, with super sensitive nipples..... tmi lol sorry

Neg preg test.. super confused

Thanks for reading and trying to help me out :)
