No advice here, just a handhold of support.
This amazing little baby you’ve grow is definitely going to want to come out, so whether you tell family now to allow them to come to terms with it, or tell them when you go into labour.... it’s going to happen and your brother and dad will know eventually!
Your parents may well be upset and angry but a lot of this will be upset and anger that they didn’t realise, that they haven’t been able to help you. If they’re angry at first they will calm down.
Is it worth writing a list of things you want to say? So
- I’m pregnant
- The baby could come any time
- What you want to say or not say about the dad - whether you want to tell or involve him.
- What you need immediately eg hospital bag items, nappies, something for the baby to sleep in, car seat.
- What your aim is long term for studies etc. I know this seems v distant but your parents will be concerned so it will reassure them if you show you’ve given it some thought.
Asking for their help with practicalities eg putting a hospital bag together or picking up some nappies, or making space in your room for a cot, will help to make it real for them and involve them. It’ll show them that you are thinking about the practicalities too.
Freecycle and Facebook marketplace will be valuable for you. People often give away or sell very cheaply baby items, as they just need the space back!
Best of luck, keep talking to us. Many mums here, some young and some older, so lots of experience.
