I Had A Preventative Cerclage Placed And I Am 15

I had a preventative cerclage placed and I am 15 weeks along. I had a cerclage placed with my last pregnancy as well but it was because my cervix was already opened. I know right after it was placed I was not allowed to take baths but after a week my Dr told me baths were fine. I took baths throughout the rest of my last pregnancy with no problems. I am wondering since this cerclage is different can I take a bath and what about swimming? My husband and I go to the lake often not to swim but to hang out in the cove with friends. Is it safe to get in the water?
