Hi I am new to all this and opks confuse me a little and I tried to google but I don’t see anything that really answers my question..
I took a clear blue advanced OPK yesterday which was later in my cycle and I got the solid smiley I took one today and there was no smiley so my question is does the smiley mean ovulation day or does it just mean peak LH and ovulation can happen in the next 24 hours or so? I wasn’t able to DTD yesterday but I did today did I miss my window ? TIA
