Is this positive?

First time using these. I have been waiting to get my period back since having my last child but due to breast feeding it’s been delayed. We want to have them relatively close in age so I’ve been starting to track ovulation because I’ve been feeling like it might be coming. I’ve had some EWCM and this is the darkest line I’ve gotten since I started using them. I’m Just unsure if it’s positive or not. Thanks for any insight!
