going for number 4

Hello ladies! I had a question. I stopped taking birth control last month. I started a new pack but only took Sunday and Monday pills. Stopped after, had no spotting either. I know ovulated on the 7th because I took a test. Hubby was out of town so we didn't get to do the deed till 2 days later. Fast forward to today and no period. It's due today according to <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>. I'm wondering if I'm all out of whack due to stopping pills? Anyone experience this before? I thought all was well since I ovulated. So confusing. Thanks ladies!
