common to have this much of a br swing???

Ok here's the problem. I play mostly low limit sng's. Average of $5 buy-in and no more than 3 at a time. I started at $100 and have managed several times to get it to $200. Lately it has divebombed from $200 to $70. I feel like i'm playing well. Paying attetion to postion, playing well before the flop as in getting away from hands than can get me into trouble, ect. I was just wondering what kind of swing in your br is normal from just "bad luck" or a bad run of cards or is there something else i need to be watching in my game. i've gone from consisantly cashing to constantly being bubble or worse. it's driving me crazy!!
