Not taken BCP for 3 nights and now the heavy begins

This morning I woke up a little tired. I went to the bathroom like usual and whoa nellie! The heavier flow has started.
Within a half hour I started cramping mildly. A half hour later, the cramping is much heavier.
Ick.
Funny thing, I haven't noticed that I had the all-day bad headache like before. I'll have to look back in my blogs but I thought the headache came a day or two before the heavy flow. Hmmm.
So, other than cramping and bleeding, today is going to be a great day! At least it's Sunday.
