Are long cycles normal after having IUD removed?

I used to have 28 day cycles with 7-9 day AF. I had an IUD for almost 7 years that was removed mid February. 2 weeks after removal my first cycle started with a 3 day AF and lasted 33 days. My second cycle was another 3 day AF and lasted 34 days. My current cycle started with a 4 day AF and I'm now at 38 days. I'm actually fairly positive that the day Glow predicted for me to start AF I was ovulating. Is this common? Will my cycles go back to the way they used to be eventually or should I get used to the long cycles with short AFs?
