IUD Removal - how long until period?

Mandi 😈💀 • Expecting #2 August '15!
Hi ladies, 
​I had my Mirena IUD taken out 2 and a half months ago. I had some initial bleeding, it lasted about 2.5 days, but I haven't had a drop of spotting or anything since. How long did it take you to get your cycle back after Mirena? I've taken a bunch of HPTs, all BFNs, not even a "maybe I see a line?!". Also, how long did you want/think I should wait before I talk to my gyno about nothing happening? I had the Mirena in for about 7 months.
