Twins & Brown Spotting

Alexandria • 24 years old; Twin Girls EDD March of 2015 ( or sooner )💕
Any other ladies expecting twins but also experiencing light brown spotting? ( I've already went to both my Obgyn and maternal fetal doctor and they both said it's nothing to worry about, and babies are doing perfectly fine) I've read plenty of times over that it is very normal when carrying twins or multiples but I was just curious as to anyone else experiencing this?
