Chemical pregnancy-normal??

So i’ve had a chemical before and this time just felt SO different. Had the positive test that faded away but what threw me off was how physically terrible I have felt. Fatigue that made me sleep all day, nausea and bad migraine that has lasted days. I also bled only one day.. it was heavy! But the last time I had a chemical I bled 7 days.

Has anyone experienced such a weird early miscarriage before?? I was exactly 5 weeks when I bled.
