am I close or is it because of different brands? MORE PICS ADDED

[kirstybumx3]

My ic OPKs arrived yesterday so I did one last night and got the darkest line I've got so far. Did another this morning with fmu (I know you're not supposed to) and got an equally as dark one. Now I'm wondering if these are just darker because they are a different brand or if I am close to O?
I'm trying to hold my urine til lunchtime now and I'll do another but this time I'm going to do two I think. One of each brand so I can see the difference.

Ps. Would that bottom one be a positive or nearly?

ETA: the bottom two on this next photo have been done today with smu both at the same time. Now the new batch has a lighter line than yesterday but I've got the darkest line so far on the original ones I was using. OPKs are so confusing. Any opk experts have any input? Please?

Omg. This photo is bad because the light bulb has gone in the bathroom so I had to use my flash in the dark
But now I'm thinking maybe today's smu wasn't a long enough hold. I've just done the very bottom one on this photo and it's even darker. They look as dark as each other in real life. Is that a positive?
We are going to bd tonight, when else should we? Anyone help please?

Just come over from our post. I find the best time to do my opks is about lunch time, I seem to get the best lines then.
Also I always get rubbish results with these types of opks so I'm not the best one to read.... however I would say you are close to O but I reckon you might be a day or so away. I would def BD tonight but I would also do another tomorrow lunch and see if it gets any darker! Good luck!
