Getting pregnant after Mirena

TTC after IUD. I had Mirena in place since 2009, changed in October 2014. The second one was in place for one year two months, grand total of IUD time 6yrs 2 months. Me and the hubby decided it was time to TTC our 3rd and last baby in December. 12-19-2015 IUD was removed had AF 1-6-16 which was normal length and flow. I guess my question is for you guys is how long after IUD removal did ovulation begin. I'm having no signs and I'm on CD 14 of a 28 day cycle. Normally I would be ovulating by now.
