I don't know what to do:/

So im in a really tought spot. I've been with my boyfriend for 5 months. I feel like i want to break up with him because im not happy but then i don't because i am. I recently found out im pregnant. I haven't told my parents but i know they are extremely against teen pregnancy. (19 btw). If i stay with my boyfriend i could possibly move in with him but im not really happy. If i break up with him i will possibly have no place to go. Im so confused and don't know what to do:/
