Just found out im pregnant and not the happiest =/ am i wrong for this?

my bf on the other hand is very excited.. he wants to move into an apartment together next month so he can take care of me and we could raise the kid together.. rather then him coming to my parents and not being able to spend nights with the baby often etc.. by the way i am 19 will be 20 this year.. but i am just very overwhelmed right now.. i never wanted to be pregnant this young i wanted to be in a good place in my life finished with college and have my career going.. now i feel like my dreams are smashed.. and i don't feel like i fully enjoined my teen years and now being pregnant i never will.. my bf is a control freak! not looking forward to that either we have been together pretty much 3 years now but i am growing annoyed of his controllingness .. not to mention how upset this will make my parents... i had plans and goals but one pop of a condom and now i am 19 and pregnant =/ may not be that young but it seems pretty young to me.. i considered an abortion but i don't know if i would really be able to go through with it.. ughh i need advice
