Tmi question, no pic.

I am 3 weeks postpartum, and I've been noticing a vaginal tickle/itch. The bleeding had slowed tremendously, and is now a light pink or brown (like the tail end of a period). Is anyone else experiencing this weird feeling and is it normal? I had a tear in my vagina (2nd degree that needed stitches) and two 1st degree tears on the outside (one on the labia and one near my urethra). It no longer hurts but this tickle is driving me nuts. I don't think it would be a yeast infection... I've only had one in my life and was caused by antibiotics. I didn't have any antibiotics during or after delivery.
