I've always used first response line ovulation test and never had issues with getting strong positives every month, but I heard the digital was way better so I switched up and bought clear blue digital ovulation test. I've been using these for 2 months every day at the same time 1 pm like I used the first response and I havnt got 1 positive smiley face yet. This is very disappointing and I'm confused. Is it me or these test? I had got my positive every month before with first response......
