36 weeks and wondering if I should avoid swimming?

Hi ladies - hope you are all well! Our neighborhood pool just reopened and I have barely exercised for the past few months bc of gym closures/covid. My husband thinks swimming will make my muscles and joints less achy and I really want to go swimming, but of course I wonder if that is unnecessarily exposing myself and the baby to the virus. What do you think? Also sane question for getting nails done - it's been forever, and I can't imagine I'll have time for either for the first few months with the baby, but it's not worth risk, etc. Any thoughts welcome!
