7 days late, wacky cycle.

So my hubby and I are not trying but not preventing. We're newlyweds and have been married since October. My periods have not always been the most consistent. They had been doing pretty well until the beginning of the year when they started to have some spotting in between. Back in March, I was supposed to get my period on the 24th, it came the 26th, but wasn't like my usual period. It was brown blood at a light flow the whole time and I had it for a full week when mines usually only 3-4 days max. Then two weeks later, on April 11th, I got my actual normal period that lasted 5 days. So May 6th, hubby and I were intimate and for the first time (insanely, first time in 8 years of being together) he did not pull out and did not use a condom. I am not on any forms of BC.

I was supposed to get my period May 9 (according to my other tracking app) or May 12 (according to Glow). So I'm anywhere between 3 and 6 days late. I have been feeling extremely fatigued and sleeping a lot and I was nauseated for two random days, which I never am like that when pmsing. I normally only pee maybe 3 times a day. I'm at work tonight and I've peed at least 8 times in the 7 hours I've been here. I took a test two nights ago and it was negative but now I'm wondering with my wacky cycle, could I have been ovulating the 6th and could I potentially be pregnant?🤔 Or am I just overthinking?
