No period 3 weeks after Mirena...

I had my Mirena taken out 17 days ago. I only had it in for 4 months, my doctor wanted to try it and see if it helped with cramping and such. I spotted (very lightly) for 3 days. I had my period while on Mirena, but it was irregular. I haven't had any spotting, bleeding, nothing of that sort for 14 days. I know it's not long but we have been doing the BD every other day and I want my BFP. Anyone else have a similar experience?
