Uncertain test result

Joan
Hi all,
I've noticed a lot of women getting great answers on here so I thought I'd give it a try. My husband and I are trying to conceive and have been diligent about having sex on my ovulation days. I took a test yesterday, my period is due in 2 days, and I got two lines one of which was very faint. It took time for the lines to develope and normally when I've taken a test with a negative result its immediate. I took a second test which also had a second very faint line. This took even longer to develope. I took a 3rd test, this one was digital and it said no. I'm so confused. I don't think that I ended up getting very much pee on last digital test does this matter? I've attached a photo of the first test and second test, the pink one is super faint... Am I going crazy?
