Bathing suits and the beach...

I'm going to the beach in a couple of weeks with my husband and another couple. I have not gained any weight yet, but my tummy is already poking out 4 whole inches farther than it was the day I got my two pink lines!! That seems like alot to me. And I feel like I just look fat. My husband says there is no reason to waste money on a tankini since I wouldn't wear it again after the baby weight is gone. He thinks I should just wear my normal bikinis. I'm about 9 1/2 weeks along. Will be a little more than 11 weeks when we head to the beach. Is anyone else poking out this much this quickly? And what would you do? Bikini or tankini? I will be a first time mom, so this is all new to me. Thanks for any help I get!!
