Clearblue Digital Advanced OPK

Hi all hope you all ok!

So but of background I had a mmc in feb and have been ttc since March and was using clearblue then took a break from them last month. This month decided to test again. I have a 29 day cycle so started testing on CD9 as per instructions. I got a low followed by a peak (solid smiley) on CD10 this shocked me but I think I’d had EWCM on CD8 and CD10 managed to BD on both dates as we do every other day. So I thought surely that’s early so I waited for the peak to disappeared and tested again on CD12 and got low. Then from CD13 I’ve gotten high I didn’t test yesterday but did today CD17 and got Hugh again. What is happening....has this happened to anyone before? I’m confused did I ovulate early or not at all....
