I will be playing a bloodrager soon and I have feats needed for my concept. However, there are one or two feats I would like to get early but there aren't enough slots.
Besides being human are there any other ways to get extra feats?
Don't worry, exploring strange concept are what new books are for. I'm positive that in a new book there will be a feat that makes you do what you want, like taking 2 feats. Probably balanced since you can only take it once.
You can still dip fighter. Just use your regular feat slots for the noncombat feats and the fighter bonus feats for the combat feats I'm sure you'll also take.
PFS has an ocher rhomboid ioun stone (using it moves your alignment one step closer to evil) that grants a bonus feat. It's a curse, so a break enchantment can remove it. The ioun stone itself is valued at 30,000gp total (so you could price a magic item that grants a bonus feat along those lines).
