Feeling confused

I have gotten a blinking smile face for the last 8 days on the clearblue opk. I typically get a positive opk on cycle day 17.Today is cycle day 17 and I still have a blinking smiley face. We used preseed for the first time last night and bd'd a couple times. Today I woke up feeling very bloated. I know it's too early to tell if it worked or not but feeling very confused with the fact I've had multiple high fertility days, and still haven't reached peak. This is the 3rd month we have been trying to conceive, first month using preseed and digital opk. Any word of wisdom or success would be appreciated.
