Need advice plzzz!

Hey ladies, I tend to overthink things. I was due for my AF on Feb. 2 on the 4th I started lightly spotting. Took a test prior to the spotting ( early morning on the 4th) BFN. Next day I experienced semi- heavy flow very clotty. Then on the 6th very light spotting then Med. Flow. Now for past two days very light spotting. This is not normal period for me usually right on time and med. Flow for about 4 days. Any advice for a gal would be very much appreciated: )))!!
