Some advice would be nice

My cycle is usually 24-28 days, I m/c for the first time in Feb. and my cycle was very strange. I bled for almost two weeks, and off and on for the next couple of weeks. My periods seemed to be coming erratically, and I found out I was pregnant again in Oct. I had my second m/c. I only bled for 3 days. 24 days later I got my period in November. Dec period was late arriving at day 30. I'm now sitting at cycle day 30, and no period.

I took a test a few days ago and it was negative. 

Are my hormones still messed up? Has anyone else experienced this?
