Fertility forums, social media circles, and other online support groups can be a huge help when you're coping with infertility.

Online fertility buddies can help you feel understood and less lonely. That said, when you're new to fertility forums, the lingo and terminology can make you feel left out at first.

The good news is you'll likely learn the new abbreviations quickly, and learn to appreciate them as they'll save you typing time!

In the meantime, if you're not sure why a forum member wants to be your CB and is urging you to BD, don't be shy about asking what they mean.

Everyone was a newbie at some point and understands what it's like to feel clueless.
