Period for a month!

Hey Ladies! 
I need to know if anyone else has ever experienced what I am going through right now. 
I am going on my 4th week of having my period and I am freaking out! 
Let me give a little back ground 3 weeks ago I started my period a week early. I was really stressed at work and preparing to go on my first long term vacation from work. I didn't want to have my period so I continued to take my BC pills hoping that would stop it. It worked for the most part but I was still spotting mostly at night (I take the pill in the morning). 
I left for Europe from the US about a week later and the same was still happening. Spotting (blood was dark red not bright like fresh blood). This continued through my entire two week vacation. 
I got back from vacation and stopped taking my birth control and immediately started what I think is my "regular period". It's been 4 days so far and the blood is medium flow and bright red. 
No other symptoms. 
Please help! Should I be worried or has my body just been through a lot with stress and overseas traveling???
