OPK Question HELP

Heather

Hello ladies. So my husband and I have been TTC since October. I've done OPKs in the past but not this particular one. I am currently using the clear blue advanced where it will give you a solid smiley (peak) or flashing smiley (high)  or blank if not ovulating. This morning I got a flashing smiley. When should we BD? How many days about does the smiley turn solid? Thanks for the help!
