Levlen ED is the only pill I've been on, other than the mini pill whilst BFing, and every time I start back on them the first cycle I get spotting around ovulation so that could be what you are experiencing, I've never had any issues with Levlen and right now I'm very grateful for it, since having DS2 AF has been all over the place, cycles ranging from 22 to 37 days. This is my second cycle back on levlen ED and I had a sugar pill yesterday on CD28 and AF arrived so fingers cross that means she is starting to sort herself out
