Help. Need some insight.

Hello ladies,

I took a pregnancy test 2 days ago and got a faint line. immediately after taking the test I started cramping and spotted for a few hours and it stopped. the next morning I started to bleed heavily. Not as bad as my normal period but heavy. I had some clots that were not normal red color so I figured I was passing tissue from the pregnancy. during the day I felt more tired and queasy like I was still pregnant but just chalked it up to hormones. today woke up feeling the same way and decided to take a test. it came back darker that the previous one. Has anyone experienced this? I've had a miscarriage prior to this, but my test got lighter right after I started bleeding and took a while to go away but it never got darker. I enclosed the first test and today's test. still bleeding heavy not as bad as normal period, and having cramps but they feel like day 4 cramps instead of day 1 cramps.I hope it's not to confusing. Thank

You
