help??

Anyone ever had a burning feeling before they went pee but not during?? I've been having a few symptoms of pregnancy like spotting for a couple hours, I'm sick and I don't get sick easily I googled that getting a cold can be a sign, I've been tired, I've been gagging at a lot more things. But then I felt this burning feeling, I've had a UTI before and it's nothing to that extent, and it's not a constant feeling it comes and goes throughout the day. I've taken a few tests I feel like I see a faint line but I can't tell if it's just my eyes making me see it, I should be getting my period Monday or Tuesday. Just wanted thoughts because I honestly don't know what's going on with me..
