Advice

Hey I would like to get some advice , I was due for my period on the 9th I didn't get it but on the 11th I spotted the tiniest bit. Normally with my period come very bad cramps sore breasts and moodyness (my BF is a saint for putting up with it) but that also hasn't come. On the 15th I took a test as soon as I woke up that morning and it was negative so I've just been waiting. Yesterday I woke up and thought I had it cause I wiped and there was blood I put a tampon in but after that wipe there was nothing else (sorry for details but the tampon was completely dry nothing on it and still nothing today. Anyone have any advice like with spotting more than once and a negative test could I still be pregnant?
