Clearblue Advance Digital Ovulation Test

I brought a new one last night just for the sticks inside but I decided to use the digital reader also and just a few mins ago I used the new one and the one I already had. The new one gave me circle "Low Fertility" and the one i already had I've been using since my cycle went off ( my cycle of went off on 1/17) but on the one I already got it gave me a smiley face "Peak fertility". Is the new ones supposed to do that ?
