Help odd smell!!!

So lately I've been getting this odd smell coming from my yoohoo I know this is a tmi but the smell (to me anyway) is like a mixture of period smell and something sweet I'll even smell it shortly after getting out of the shower it has more of a sweet smell then anything and it's not like anything I've smelt before so that's why I have a hard time describing it should I go have it checked out? Has this happened to any of you? And what was it?
