I was planning on stacking my hbc (lutera) this month. I took the first pill of my new pack yesterday and fully skipped the placebos. Now I'm feeling a little crampy and have thicker discharge so was thinking about just going through the normal period. So could I just start taking the placebos now and start the new pack next monday? I have a few extras of an old pack, so I would just use one of those for the first day. Would that be ok? Any compromise of protection or any other possible concerns?
