TMI just asking

I missed my period by a few days, and the morning I wake up to take a test , there goes “MOTHER NATURE” but this time it was different, the cramps was worse than ever ! The blood had clumps in it and it was just crazy!! So that night I woke up and vomited everywhere!! I was drained and felt horrible, and on top of that I had to pee like every 25 minutes. Any ideas on why?
