Im pregnant with baby 2#

Basically I'm 20 nearly 21. My partner is 22. Found out this afteenoon that I'm pregnant very early on about 3-4 weeks I'd say on the home pregnancy test. Already have an 8 month old baby girl. I'm more concerned about what my family may think as they said wait till my daughter is about 2/3 going into nursery to then have another child. I have no idea what too say to my family. My papa he will be angry and my big sister plus my mum.

What will I do. Both myself and my partner wanted another baby but we didn't think it would happen so soon after our first baby was born

Thanks
