PLEASE HELP

Your last period was May 5th...it's only May 17th right now so you're not even close to being due yet. Are you pregnant? Well, if you don't know, how could we possibly know? You will need to wait until you miss your next period and then test some time after that.

It is likely the light bleeding is from having taken the ipill. Your next period may or may not show up as expected... some women will have an off cycle at first after using the ipill, others will be right back to normal.

As odinn7 said, wait until you would normally expect your next period. Test if necessary at that time, as even with using the ipill, pregnancy can be a possibility.
