Period after Mirena...

I had my Mirena in for 12 years.

I had the 5 year so over the 12 years I have had 3. I had it removed 05/23/18 and didn't get a period till around 06/25/18. I've been bleeding since. Anyone have the same issue. My husband and I are TTC. I just turned 35 and my youngest is 11. I had the iud removed in hopes of getting pregnant. My periods use to last 7 days'ish. This is a bit discouraging. Advice please.
