I have an appointment to get nexplanon which is the birth control inserted into your arm. My gyno gave me birth control pills & ive been taking them every day but not at the same time like you're supposed to for it to work. She also told me not to have unprotected sex but i have been like every week. She told me if i did i wouldn't be able to get the nexplanon. But I'm pretty sure I'm not pregnant...would i be fine to get it?
