What seasons do you find you get the hint that Rachel is pregnant?

Idk which FRIENDS TV show you guys are all watching, but at the end of season 7, Monica and Chandler get married and Rachel tells Monica and Phoebe that she's pregnant. She also takes a test at the wedding ceremony. And then in season 8 she tells Ross he's the father :)

7. At the wedding they find out. 8. Ross finds out. 9. She has Emma

The answer is 7. "The one where Monica and chandler get married pt 2" is the last episode of season 7. We find out it's neither phoebe nor Monica pregnant and the camera pans to Rachel. Then season 8 Rachel is pregnant. Gives birth last episode of season 8 Emma is born. Boom.
