Hi Bethany,
I BF'd also for over three months (just starting to wind down) and also noticed some stinky BO. Worse still, Id use Lavender scented Secret, so I smelled like a stinky flower. :-) If you want to try a stronger deodarent, try Mitchem for women. ITs really good at stopping the stink, but it carries a higher concentration of aluminium (I think), so it may also may clog your sweat glands. I wish I had a better suggestion for you - I ended up not raising my arms very much.
Good luck!!
