Am I just over excited???

my husband and I have been trying for baby #2 for about a year now. We got pregnant last December and ended up losing it at 6 wks.
​So for the past 3 wks now my bladder has been working overtime. I've been going at least twice as much as usual, even waking in the middle of the night to go. I've become quite sensitive to smells (not that they make me nauseous but just stronger) , my boobs have been super duper sore and the past few days I've been nauseous but haven't gotten sick.
​I took a PT yesterday and thought I saw a faint positive, but AF Is not suppose to arrive for 6 more days.  
​I don't want to syke myself out thinking I could be when I'm not, but the signs are all here!
