HELP ME PLEASE

I been off nexplanon since Nov 6, 2017 . I had irregular periods however my last 3 cycles has been the same . I had my AF on June 27 ... I Baby danced July 5th, 13th and 14th . My <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> told me I ovulated July 13th . I had very light spotting pinkish / brownish on the 16th that lasted a few hours. But after that nothing... My period due on July 27 . I know everyone is different.. I was wondering if there is a chance that I’m pregnant or could be. I would love any advice or to hear from anyone that was or has a similar situation to mines. This never happened to me before.
