Sex in the first trimester.

Just wondering how many people have asx in their first trimester?

Do you cramp afterwards?

Has it every caused any problems with your pregnancy?

We had sex with out first a couple times in the first trimester, and now I'm pregnant with baby #2, I'm 7 weeks and we've had sex 2x. Sometimes I worry we'll cause stuff to go wrong... but I always feel fine afterwards.
