We got 'back in the saddle' at about 3-4 weeks after, because I had heard that it was best to at least attempt it before your 6wk check, just in case something wasn't right and you could ask about it then. I was so pretrified for the first time - it was worse than doing it for the very first time LOL! It was fine and we had no issues, but lots of KY and foreplay is all I can suggest.
