So, I've been on Demulen 30 for over 2 years, and I've only missed a pill once in the whole time I've taken it. I'm really good at taking it at the same time every day. I wonder if the longer amount of time you've been on the pill, the more protected you are? I've been more sexually active as of late and I'm curious about it. Not trying to be pregnant, lol, just curious to see if that's true or not.
