Maybe pregnant?

Ladies, what were your first signs that made you question you were pregnant before a missed period? I’m not supposed to get my period for another 7 days, but my boobs hurt like CRAZY! (They very rarely get sore before/during my period). I also have a strange headache, my stomach feels weird and I’m extremely exhausted. I also had woke up and was very lightly bleeding so I thought it was my period coming early. I stuck a tampon in and just took it out and there’s only a little very light pink blood on it. Please don’t judge! I’m just asking because I want to know how you guys questioned if you were pregnant or not! Obviously once and if I miss my period I’ll take a test. Thanks in advance ladies! 😊
