Viscous gunk after suddenly stopping sexual activity?

i broke up with my boyfriend of one year about three weeks ago, and we had been having sex regularly the whole time we were together. i've never been crazy about masturbation (for me, no element of surprise = no orgasm), so i really haven't had any stimulation for three weeks. today in the shower i noticed my vagina had a lot of whitish, clear, viscous gunk inside. is this just my body reacting to lack of sexual activity, or should i be worried? please respond, thanks.
