On Period for 2 weeks straight, it's a first for me!

Hello, I'm a 31 year old mother of one and my periods have been consistent. For the last year I would become moody 1 week before my period, have my period for 4-6 days, and then be done for approximately 5 weeks. This is the first time I have ever experienced a 2 week, going on 3 week period. I first started of with light spotting. There would be days when it would be heavier, but only for a day then it would go back to spotting. Coming into the 2nd week, I started getting blood clots in various sizes. The regular blood coming out has no funky shades of red, there is not any odors, and no cramping. I did feel myself ovulate last night though which made me a little light headed, but that's normal for me.

My personal life history may have something to do with it, but not quite sure. Spring 2008 I was taking 6 classes at a local community college. I had an emotional break down because my boyfriend and I broke up early in the semester. Both events combined caused major stress in my life. In the beginning of May is when things started to improve in my life and I began to be happy again. I met up with an old friend and we started hanging out. I just got back from a two vacation in the Mid-west. My friend made a comment about climate change and I thought that was a little far fetched until I read someelse's post. The only other significant change in my life that happened was that after 7 and a half years, I became sexually active again.

There are a lot of possible factors, but I think my body is responding to the fact that I'm doing things it's not used to. I would like some feedback to hear what other people think. I've considered birth control pills, but I do not like the sound of the side effects in them.
