Running out of positivity!

I've been ttc for about 3 1/2 years, and every month is just one huge let down. I can't wait to have a baby. Even if it's just one, at all, lol. Anyways, I need some advice.. I've taken three hpts, one on Friday, one Saturday, and then one this morning, and while the one this am was a huge Bfn, the other two I'm not so sure about? Any advice?? I tweaked the pics just a little.

Bottom left was Friday's test, top pic was Saturday's, and bottom right was today's. All taken within the 5-10 min suggested period. Thanks in advance ladies. I just need some encouragement before I rip out my hair lol. Baby dust to you all!!
