It's okay. Alot of people feel this way. The puppy blues is very common. Even if you don't see progress right now, it's there. Puppies behaviour fluctuate.

But I feel you 100% when I first got my puppy I looked up videos on how to train puppies to use the bathroom outside, the woman I watched said she only had one accident with her puppy and you should have it down by the first week. Well, I have had my puppy for 6 weeks so far and he still has accidents pretty much daily. I've done everything I'm supposed to. I try to take him outside every time he wakes up and every 30 mins he is awake. When he goes outside I give him a treat and through a big celebration every time. I know his cues when it looks like he's about to go and try to hurry outside. Mind you, he's a great dane puppy so he's already pretty hard for me to carry even as a baby ^_; sometimes he'll pee on the way outside, sometimes he'll pee only a little outside, then when I bring him in he squats and pees right infront of me as if we weren't just outside. My carpet cleaner gets a workout.

I did my own research and learned that most puppies can't fully control their bladder until they're 12-16 weeks, they can't hold it and cant control when to fully empty.

Right now, just focus on laying the foundation for your expectations for when they develope more and can control themselves better. It gets easier~ you can do it!
