Plus Sized Maternity Swimwear

Does anyone have any suggestions for *modest* plus sized maternity swimwear for active swimming (e.g. swimming laps, water aerobics)?

I am considering this suit from Lane Bryant at the moment:

But I'm wondering how far into pregnancy I'll be able to wear it. I also am not sure how Lane Bryant typically fits. I am 5'9" and currently a size 20/22, 250 lbs. The last time I bought a suit for active swimming I was 173 lbs, size 10/12 so this is totally new territory for me and I feel lost!
