Ovulation tests? New to all this...

Yvonne
Hi. I am 32 and my husband and I have been casually trying to get pregnant. OBGYN said to just make sure to try on days 11, 13 & 15. OK. It's been 5 months and nothing. Friends swear by advanced clear blue digital, so I started testing this month. I had 4 straight days of flashing smiley faces to show my estrogen levels are up, forgot to test one morning, and then today also got another flashing smiley... That seems like A LOT of flashing smiley to me. Still haven't gotten a sold smiley face to indicate I am ovulating... On day 14 of my cycle. Anyone had any experience using these tests?
