Had a positive opk 4 days ago. Toke clear blue digital today and it had a flashing smiley face? But lines are very faint on a normal opk. Can’t understand why I have already had a positive opk and 4 days later a flashing smiley today. I’m confused 😭😭 clear blue digital yesterday was completely negative. I know your not suppose to test after your first positive but i was just curious I guess
