How long does it take to regulate period after IUD removal?

So I've had Skyla in for 3 years now. I bled constantly for 2 or 3 weeks after the painful insertion then almost no periods for 3 years. I have had occasional brownish spotting once every few months then nothing.

I am getting my IUD removed in 2 weeks and I am so excited. We are beyond ready to TTC.

Have any of you had Skyla and had no periods? Did your periods resume after removal? How long did it take to regulate? How long did it take to conceive after removal? I know everyone is different. Just trying to get an idea. Thanks.
