Pregnancy symptoms still after period, what could it be??

Ok so I got my period 2-3 days early, it was a light period (with so many different colors) with a lil bit of clots but my symptoms stayed throughout it and still now. It lasted for about 5 days (with most days just spotting) and on the last day spotting I took a test cause breast and nipple pain during period is NOT normal for me, and it was BFN of course. What could it be? I'm 9 days from the end of my period and still have some nipple sensitivity off and on along with a lot of other symptoms.. I'm scared to test again cause if it's negative that means I'm either going crazy or something is wrong lol
