Am I over reacting?

So my boyfriend and I have been together for a month and a half, soo early lol, however he doesn't communicate with me as he use to at first, and now our sex life has been off. TMI, but I like having sex and we use to have it every other day when I would see him, but now it's only once a week or so. He does have his own business and also has other things going on, so I know sometimes he is busy. Should I be worried or no?
