How many days after the first day of your period do you start testing with OPK?

I’ve seen information online about avoid “rigorous exercise” but have a hard time judging what that means. I am a casual runner (like 9 minute miles, average 3 miles a few times a week), is it okay to keep doing this while TTC? What about during my ovulation/implantation window? Stories/advice from other runners is appreciated! Thanks in advance!!
