Sickness?

Ok so today is Thursday.On Monday I started to bleed (a little on Monday then the next 2 days it looked like I was on my period...but I wasn't because I had my last period 2 weeks ago,and it only last like 3 days)my thighs and but have been sore amd kinda hard to move.I stopped bleeding on Wednesday then later that day at 8:30-9 my stomach started feeling wierd and like I was going to puke but not right at that moment,so I went to bed by 9:30 but on Thursday morning (1Am,1:44AM,2Am,2:30AM is mainly around those times)I started puking,I don't know if I'm sick,or if it's something else.
