So I just got my IUD taken out...

So I just got married on Aug 15th & my hubby said once we were married we could start trying for a family! So I got my Mirena IUD taken out on Sept 3rd, woo! Well, I know it's highly unlikely for me to get pregnant until after my first period after the removal because my body has to shed what's left from the IUD. But my prediction calendar says my period should have started a few days ago. Has any one else had this issue? Pretty sure I'm not pregnant yet since I just got it out, but I'm not stressing over anything so what else would cause me to miss my period? 🤔🤔
