Can’t Remember OPK

Baby #1 is 20 months old and I can’t remember anything about OPKs 😅

Top two are from yesterday (CD 14) around couple hours apart. Bottom is from today, CD 15, about 2 hours ago.

First, is the bottom positive right? Both lines are so faint!

Second, since they are all looking positive...when will I ovulate? Should we BD tonight?
