Do you think I ovulated? Currently 9dpo (I think)

Ab

Hi all. This is my first month temping. I got a very dark positive OPK at CD15 (first time this early, usually it’s around CD20). I didn’t have any EWCM this cycle either like I usually do, just watery CM.. so just wanted your opinions.

The temperature at 3dpo was taken half hour earlier than usual, so not sure if it should be discarded.

If I don’t get a bfp this cycle I will invest in a BBT thermometer. Thank you in advance! :)
