Lo Loestrin and extremely light period?

I'm on my second pack of Lo Loestrin and have had no problems, but I was puzzled by my "period" (or lack thereof, really). I BARELY spotted on the two white, estrogen-only pills at the end of my last pack and had zero spotting on the single brown placebo pill. No cramps at all.
Is this just a first cycle kind of thing? I know it's not uncommon for women to miss their periods while their bodies adjust to the hormones in BCPs. That said, have any of you ladies had a similar experience with LLE? I'm wondering if it will be like this the whole time I'm on it.
