Hello, I Have Missed My Period For About 10 Days

Hello,

I have missed my period for about 10 days now - I did a pregnancy test 3 and 7 days after missed period - both times it came out negative. I had some signs that seemed pregnancy related - my breasts hurt for almost 10 days, I was feeling tired, have been loosing breath, having mild cramps, no apetite. But yesterday, 10 days far missing my period bright red and watery blood broke. I had mild cramps. Since I use a menstrual cup - it was about 60-70 ml blood over 24 hours. All of it was unusually red and liquid. My breasts are not sore but still rather full. Am I pregnant or is there something else wrong? I must admits I had an unusually stressful month leading. To this period. Thank you!
