I wanna test!!!?!??

So for no reason I just want to take a test today. I'm not supposed to start AF for a few days but I just want to. Sore boobs for about 5 days and more discharge then usual for about 4 days. Are these signs or wishful thinking. I don't have any tests on hand so I would have to go buy some and I'm super broke and it could be a waste of money. If I am pregnant then I will find out naturally soon but 😝 who wants to be patient.
