Still super faint line...

Hi ladies. Just hoping you guys could help me out a bit. I tested on Friday and got a super faint line and that's all I've had since. I feel like I have to pee all the time and I've been going at least once, if not more, a night. Could the lack of line progression be because my urine isn't strong enough? I'm going to try not to test for a couple of days. I just thought that I would be seeing a darker line by now. I should be about 12 dpo right now. I'm so worried because I had a chemical last month, but even then the line was faint, but much darker. Also, I know the bottom one is really hard to see in the picture, but there is a line, just crazy light, but it was taken at 6am and I peed around 3:30am. Hopefully it's ok I post here, I didn't know where else to post since it has to do with faint lines and I've seen a couple other progression questions.. Maybe I'll post in the general ttc room also. Thanks for any help.
