I got a big problem

So i just found out i’m pregnant again..and i’m only 17 i already had one abortion . And again it happend because of a protection failure. I’m taking birth control and we use condoms and i still got pregnant two times within 8 Months . I’m so scared too go too my doctor again what does she think of me probably she won’t even believe me that i know how protection works . I’m embarrassed and i just want too disappear. It’s horrible but i definitely can’t keep the baby . I’m so busy with school and work and all that stuff it just does not fit in yet..what will people think about me..that i’m stupid :( even though it was not my mistake . I need some advice . If i go too a new doctor will she know that i already was pregnant? And did any of you had already the same problems? I just feel so stupid and idk 😐
