Chemical pregnancy? Or Early period? Or pregnant?

I’m going to the obgyn anyways but I just wanted to post. I already had my period at the beginning of the month (my period only last 3-4?days) and then bled 2 weeks after that period for 6 days with now slight discharge. It came out brown at first then kept changing to a brown pinkish, bright red, dark red with some clots. Extreme stomach pain cramps , swollen breasts, body aches. Now breast back to normal mild to no cramps. I took a test it had a slight slight line, second test negative and took pee test at hospital negative.. now I’m scared this has never happened before I’m not sure what this means at all. And also had an asthma attack when I went to the hospital (body shaking uncontrollably everywhere) but my husband said from my waist down and lady area was shaking rapidly. HELP
