Stopped my anti depressants, removed my iud, no period.....

So I got my period 40 days ago, they stopped after 8 days, on the eighth day I had my copper iud removed as I felt it was causing a lot of depressive issues,

I stopped my anti depressants (stopped them within 10-14 days, I was only on them three months and yes I know that’s quick to ween off them)

I did have unprotected sex with my partner 5 days before I removed my iud, he did ejaculate in me, I WAS given the morning after pill the same day as iud removal as a precaution,

It has now been 41 days since my iud removal and anti depressants have been removed or withdrawn from my system and no period.

Back story; before iud period was about 5 days and light to medium with 1 or so heavy days 8 day cycle

With iud period went for 8 days 3-4 heavy days and spotting a day or two outside the 8 days as well. 28 day cycle

I’ve always been like clockwork

Had a preg test last Monday, was negative and had a blood test two days ago and getting the result tonight.

Has anyone had this happen to them or someone they know of before?
