Third day late, no period?

Nicole • 11 years together 👫 10 years engaged 💍🌈 Hayley 👩‍👧
My partner and I did a lot of baby dancing this month. I've been getting so tired that I've fell asleep for hours and then slept all through the night. Now Glow has told me that my period is three days late. I'm getting slight period pains but nothing major and my cervical mucus has almost dried but. Can anyone help?
