Advice please??? 🙏🏻

Sophie

I am 5 days late on my period and have experienced intermittent cramping, back ache, heartburn, headaches and slight nausea feeling! I took a clearblue ovulation test on 22nd May and got the peak fertility smiley face!! So based on this Glow calculated my period as due on 6th June (I have longer cycles than 28 days) I have been having increased white cloudy discharge since my period was due but have taken 2 pregnancy tests (one on Tuesday and one this morning) and both negative! 🤨 so confused as surely if I ovulated (as per my positive ovulation test) then if I am not pregnant why haven’t I had my period?? Any advice welcome as I am baffled!!! 😩😩
