TMI - periods after mirena removal


So I had my mirena out in feb, had what can only be described as a blood bath of bleeding with lots of clots for 14 days after, so I have classed that as my period because it was due anyway around that time.

So we’re ttc baby no. 2 and I believe with no luck but to be fair I didn’t expect it to happen the first month after removal. Now I am about 4-5 days late with a negative test.

How long does it take for everything to get back to normal after the removal? I heard about 3 months or so but is it right for my period to be late? I know stress and what not can cause this, but I am no more stressed than usual. Any of you wise ladies been in my situation after?
