Is it all in my head?

I have been having some symptoms but I'm not sure if they are actually pregnancy symptoms or if they are just from the progeserone. The most notable symptom is that my nips are tender and tingly off and on all day. The frequently look like they're popping out too. This is waay exciting for me because that's the biggest thing that I noticed when I was pregnant before. I have also been more tired than usual but not by much. I have been feeling like I'm really thirsty and subsequently habing to pee a lot too but that could be anything. So is it all in my head? Probably, but that's okay with me right now. I need some hope to hold on to until I get that second line!
