Opinions please??

So I have a question for some people who may have been pregnant or are currently. So a few days ago I was bleeding VERY VERY lightly and it only lasted 3 days. Usually my normal periods are 5 days and on the heavier side. I have been getting sick in the morning, dizzy a few times, been having hot flashes and night sweats. When I started "bleeding", it said I was 6 days away from my actual period which would be today and I didn't get it. I took 2 tests and they were both negative so I'm not really sure what is going on, so if I could get some help it would be appreciated😁
