We've been trying since December using Ovulation predictors for two cycles

We've been trying since December using Ovulation predictors for two cycles. Getting discouraged we talked to our OB. She took a blood test that came out normal and advised us not to do the ovulation predictors anymore and just have sex every other day of your fertility window and then some. It worked! This is five day before my period and just took the early clearblue easy digital and it was a big fat positive!!! We are over the moon.​
