Yes, that looks positive to me. It looks like 50% of it is as dark. It's hard to know Sunkissed, since this is your first time doing OPKs right? Once you know what *your* positive looks like, it'll be easier next cycles.
When I first posted the pic of mine last cycle (the pic I showed you) everyone on another board said it wasn't positive, that it was *almost there*. But I did some research, and learned that 50% of it can be as dark and it'll be positive. The people that told me it wasn't positive, prolly has much darker OPKs. But for me, most cycles mine will just me 50% as dark, and I know now that that's positive for me.
Try holding your urine another 3-4 hours and test again later tonight. It may get even darker.
Are you having EWCM? I saw your chart and it says creamy. Do you check your cervix?
