Am I in the friend zone?

I dont think im in the friend zone but I wanna be safe. Would a girl hang out with me for five weeks in a row, enough time in one on one situations but sometimes with a few other people, if she wasnt interested in me? I think im getting all the right signs and she wanted me to meet her family and i had dinner with them yesterday, also, she says her sister wanted to meet me so im going over again next weekend. Oh yeah, she laughs at everything I say. This cant be just friends am i right? Just making sure because ive misread signs before.
