Please let this be an implantation dip!?

Not really got any symptoms as such just feel different!

My apps say i ovulated 8 days ago - glow says im only 7dpo today.

Got loads of creamy lotion like CM - usually dry waiting for AF

Very tired

Had some headaches

Very mild cramps when waking up in the mornings

Thirsty even though drinking 4litres of water

Promised myself i would not test this month until period is late as wasting too much money on testing and getting BFN!
