Can you swim in cold water during ovulation if you are TTC?

Hi ladies. I have been searching the Internet for some answers and couldn't find any. Do you know if it's safe to go swimming in cold water (between 72 degrees and 80 degrees) when you are ovulating and are TTC? I went in a few times but got some minor cramps. I am not sure if these are ovulation cramps of cramps from swimming in cold water. Any advice?
