Six weeks and break-through bleeding

Started taking continuous BCP again on Sept 7th. Today, October 18th, I started bleeding. I noticed spotting mid-day and put in a tampon. Four hours later, sure enough I started bleeding. Hmm. Kinda weird that it started while I'm taking the BCPs and it's only been 6 weeks, not 3 months like before.
I won't take a BCP tonight. I will wait a week and see if I have a normal cycle.
The BCPs I've been taking are:
ethinyl estradiol levonorgestrel
30mcg .15mg
I remember from years ago, like decades ago, that when I was on a BCP I had to take a stronger dose. I think it was when most women were taking Ortho/Novum 1/35's and I had to take 1/50's.
Symptoms? Nada. I did feel a little pang for about 10 minutes earlier today, but after the intense pain from before taking the BCPs today's pain was nothing.
I don't like taking medication as I always try to do things naturally, but taking the BCPs seems to have minimized all the symptoms and I have my life back.
We'll see how this week goes....
Aloha!
