Should I consider birth control

This is my first post. So earlier in the year I began a relationship and we have currently have started having unprotected sex at least three times a month. I currently started my second year of college and want to focus on school instead of being afraid to conceive a child. About four years ago my doctor had told me they didn’t recommend birth control due to my weight and my age. But now that I’m in a relationship and I’m sexually active I’m considering going on birth control but not sure. If you can I would like your advice of what I should do anything is helpful. Thank you
