IUD removed, now TTC. possible issues?

Julie • Pregnant with our rainbow baby! 🤰🏻🌈🥰
I talked to my doctors nurse today and she said my periods could be irregular for 2 months after my IUD was taken out.(IUD was removed Oct. 30th) I am currently almost 1 week late and still getting BFN. 💔 
My periods were regular before the IUD, when I had the IUD I always got my period the same time each month but I bled for almost 2 weeks. 😞 (I had it removed because of bleeding issues) 
My cycles always went back to normal after getting off a birth control (I tried a pill pack and had bleeding issues as well) 😕 it seems like my cycle went back to normal but I'm almost a week late and still no AF or a BFP
For the ladies that had an IUD, did you have irregular periods after it being removed? Also how long after it was removed did you get your BFP? 
Thanks for the input ladies! 💕
