plan b?

Miranda
How late can plan b make your period? I took it on June 5th and I spotted a lot for a week. I had to wear a pad but it was 2 weeks before my scheduled period. My periods usually come 5 days after <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> predicts so I'm not really nervous but I still want my period to come. I haven't felt my normal pms symptoms other than being moody and my face breaking out. I've been extreamly tired and having to pee a lot. That could be chalked down to working more and sleeping less and drinking more water because it's summer. Any advice would be appreciated
