What do you guys think?

I use to different apps to track my cycle. Both has different dates on my period start and ovulation day. Not sure which to really go by. I haven't had my cycle so far this month. My average cycle length is usually like 33 days. Last month I think it was close to 40. I'm on 39 today. No sign of AF coming though.

I tested Wednesday, it was negative. But I've still been feeling off. I don't know exactly how to explain it, just off. Like for the past week or so. Today, all day my breast has had this tingling sensation. What could this be? Should I test again maybe?
