Two week period?!?!

I am very irregular, as in I am having my second period since August. However, this period started last Monday and it is showing no signs on stopping. I was very light last week but the last few days have been very heavy, and it doesn't seem like it is planning on slowing down anytime soon. My husband and I have been TTC for 8 months and this irregularity is not helping. I have an appointment but it isn't till next week. Any thoughts or ideals would be more than welcomed.
