How do I get over my nerves of going to my Boyfriends house ?

Okaay . We’ve been going out for about 11 months . We only hang out about once every month or 2 . I have never been to his house since we started dating . I have only been there once and that was for a sleepover with his sister and my friend . While I was there his parents didnt really pay any attention to us and just went to bed . Anyways since im dating him now , and we have always hung out at my house so far , im kinda nervous to go to his house . In September one of my friends told me that his sister didnt think his parents liked me (I was there a second time but I was at a friends house who lives across the street and his parents only I asked if I was staying the night with her) because im too quiet and there were some other things that I cant really remember now . I went about 6 months thinking they hated me until my boyfriend asked me and they said they didnt dislike me at all . This kinda made me feel weird about going to his house , but a few days ago he said that his mom might ask me a few questions . Also that when he told her that I would be going there next time that she looked kind of excited . This made me really nervous (his parents are out going people who arent shy to ask what they want to )

So any advice as to how I can get over my nerves ? Im a very shy person :s

Thanks
