miscarriage

So I had a miscarriage last week 😢 and stopped bleeding like 3 days ago, and tonight after a long week without the D we finally had sex again 😍 ( we've had a pretty tough week and now I definitely feel it was down to sexual frustration 😂) anyway the reason I'm posting is because we didn't use any protection and I'm no longer on the pill, i know they say wait two week before trying again, we're not exactly trying we just didn't use anything. Just wondered if anyone else had unprotected sex a week after??
