Abortion

I feel so nervous about being judged but i’m having an abortion. The contraception failed and i’m unable to care for a child in my circumstances. I’m about 6 weeks pregnant and i’m going to book an abortion. I think i’m going to choose a medical abortion by taking 2 pills. I live in the UK. How will this work? I haven’t spoken to a doctor yet, so will i take both pills at home or one at the clinic and one at home? Also i’m extremely worried about the pain. I live at home with my mum and i do not want her to know i’m pregnant. Will i be able to hide the pain i’m in? and how long will it last? I’m very nervous so if someone can share their experiences with me i’d be very grateful.
