Possibly, because it's something new to ur body, so this is how your body reacts to this. Yes it can because it's a hormone. This puts your other hormone levels off balance for awhile. I went into early menopause (38 years old because of a trauma in my life) and I got those brown spots on my face but stayed out of the sun (wore sun lotion) and wore a baseball cap or my hippy hat while fishing and they eventually went away. I still have one slight brown mark on the lower part of my left cheek.
