Pregnant

I'm 14 and pregnant, I don't know what to do. My mum knows I'm sexually active and has put me on the pill and give me condoms but I forget to take it. My mum has so much on her mind right now and dont wanna cause her stress. Can I have an abortion without her knowing

I'm in the UK

I am very close with my mum and can talk to her but she is going through a lot right now and dont want to give her anymore added stress
