So, I've been using the clearblue advanced opk. We have do have sex before peak, and I only get one flashing smiley day. Then when I get "peak" (solid smiley) we have sex both solid smiley days. Should we be having sex after the two smiley days as well? I've heard so many mixed things about the LH surge. This is our fourth cycle TTC and I'm starting to think I'm doing it all wrong 😔
