I would still keep taking the pills as normal and you should be protected. I skipped the placebo pills once to not have my period and it worked out fine for me. I had talked to my doctor first, and she said I may experience breakthrough bleeding from doing that, but luckily I didn't. It probably just messed up your system a little bit, so your period may be off. But I would continue as normal and wait to see what happens next month! Hope this helps!
