Positive opk?!

Hi ladies! I’ve used opk’s before but only once, that was in November. I got pregnant in November, but sadly lost the baby. I’m finally feeling ready to start trying again. Well, I had some opk’s in the house so why not take one? I did not expect it to be this dark already!! I held my pee in for an hour, didn’t drink anything and woke up about 4 hours ago. Would you say this is forsure a positive? I plan on taking another one within the next few hours just to be sure.
