postpartum bachelorette party

My best friends bachelorette party is about a week away and we will be spending sometime at the pool. Im unsure about how I feel about getting back into a bikini at 6 weeks pp. I had twins and I've fortunately am back to my prepregnancy weight but still have come loose skin and a few stretch marks. I figured I'd do sometype of coverup but my other concern is im still slightly bleeding. Does anyone have some advise so I don't end up at the pool in shorts to acomodate a pad and a shirt to cover up my tummy?
