When will I get my period??

I had a mc on May 21st (2nd one within 6 months) I only bled for 3 days & I was just wondering when anyone else got their period. Me & my SO has sex the following week & I'm freaking out bc I scared that I was when I may have been ovulating. I didn't think you could ovulate until after a period. We would be over the moon if I am but I'm just not wanting another mc for not waiting for 2 cycles....when should I test??
