Almost there??

So I took this within the time frame. Am I getting close? I posted the other day. This is my first time using these tests. Now should I stick with this brand or go for another online? Glow did say I was supposed to ovulate on Friday but now its saying Saturday. I'm so confused. My other apps said either Tuesday or Wednesday but it wasn't dark at all. This one is darker then the other tests I've taken.

☝️This was taken within the time frame.

☝️This one was taken on Tuesday. I took that within the time frame as well. Its lighter then today's test.
