Sex w iud

Okay so I had skyla put in yesterday, right at the end of my period, and my doctor didn't say anything about how soon it was okay to have sex again. I've seen online though that you're supposed to wait some period of time though? Just curious how long anyone else with an iud waited and/or what their doctor advised... And while we're on the topic has your iud affected your sex life? Positively or negatively...?
