10 days late on Paragard

k

Hello all! I’ve had paragard now for almost a year and my periods in the last few months have been quite regular between 30-35 days. This month is the first time where I’m actually 10 full days late. I had a little spotting and cramping around the actual time I was supposed to have my period but the actual usual full thing never came. I’m actually feeling pretty good now and I’m not really showing much of the usual signs of PMS (which I usually have pretty badly) but I’m bloated AF. I have also taken 2 pregnancy tests 6 days apart (last one being last night) and both were negative. I have changed my workout routine in the past 4 weeks and I was wondering if that could have caused my late period? I know that it can have some effects but I didn’t expect it to be over 10 days.

Opinions?
