Almost?

So I'm almost 4 months postpartum and breastfeeding but the past few days I've been a bit crampy and had some EWCM, and have been super emotional for the last couple weeks so I'm thinking my cycle may be coming back. Took an opk for the hell of it (not trying for another yet!! Was just curious) and this was my result. The premom app says it's only like .58. I know it's not quite positive yet but would you say I'm really close?
