Plan B & periods

I've taken plan B 4 times in the last 9 - 10 weeks because of condom slippage/breakage (yes, I know, other BC methods will now be in place), my last 3 periods have been plan B induced & the last 2 times I took it was in the last 4 weeks, making my last 2 periods 17 days apart. Now I'm 17 days after the start of my last period (10 days before my "normal" start date) and I feel like I'm having symptoms, mostly bloating and cramping. Is that typical? In the last when I've taken plan b (a couple of years ago), it never really messed up my cycle, but I've never taken it so close together before, and never plan to again!
