Happened to me too this month! Nothing in the morning, then static smiley. I think some people peak quickly but it also depends on how/when you take the tests ie how much you had to drink, time of day etc. To be sure I used other ovulation tests which also confirmed peak so maybe try another one? Good luck!!
Yes, I always have a rapid surge, and then it goes negative again. Some people don’t get a gradual darkening of tests.
Did you take 2 in one day?? I don’t think you’re supposed to do that with the clearblue?
How far apart were the tests? How unusual. Get BDing anyway!!
