😕 whats going on .. Strange Period

Anyone able to help? 
I started what seemed to my periods a day early which im not too worried about, its the fact that my period has never been this light, not enough to fill a tampon or a liner , sorry (tmi) i had light bleeding/spotting  for 2 days, then it stopped for a day, now im spotting again  😟 i have all these spots which i never usually get, my nails have become very brittle and dry ...Â
