Iud removal

Skyla
So I had my mirena in for about 1.5 years. I got it removed March 20. I didn't cramp
Or bleed or anything but the next day I did have some white discharge that seemed like discharge you have when ovulating. I never had a period while on the mirena just random spotting and cramping.. The 25-26 I had super light brownish pink spotting. Do you think that was my period? My husband and I have had sex just about every day since having it out. But I have no idea when my fertile time will be since I haven't had a period. How long did it take for you to start your period after if you didn't start bleeding that day? Is it possible I could be pregnant already? I've been super tired, and had minor cramps just about everyday, my lower back hurts, but no period :(
