How many of you ladies have used the Clearblue Digital ovulation test? This is the one that gives you a circle or smiley face for your LH surge. I've been using first response and decided to switch it up this month. I have been getting a lot more cm starting early this morning and is just increasing more. I think it's almost time. What do y'all think? We have been TTC for 14 months now and really hoping our time is soon. We also got Pre-seed to hopefully increase our chances. Any luck using this brand?
