2ww and "feeling it"?

Hello ladies! I am currently in my 2ww. We have been trying for about 3 years but still nothing. All my friends who have managed to become pregnant always says that when it finally happens you "feel it". That you feel it in your body in some way, even before you can take the test. I've thought that I "felt it" every month so far, but then that damn period comes and I'm proven wrong. So my question to you pregnant ladies is: Have you experienced "feeling it"? And if so How did it feel?
