skipping last placebo pill?

I'm on Lo Loestrin Fe and kind of started my period on the first white (progestin only) pill. I have only one more placebo pill to take (my brown iron one) and I kind of just want to skip it (since I've already gotten my period) & just start my new pack of pills. can I do that? or do I have to fully complete my placebo pills now that I've already started them?
