Starting to think I might be pregnant

Wholly molley I’m three days late I feel sick 🤢 and my stomach is cramping I’ve had spotting which isn’t normal for me and now I’m stressing about it

It’s Good Friday tomorrow so I can’t even go get a test as all shops will be closed

I don’t know what to do

I’ve always wanted to be a mum but this isn’t a good time as I’m the sole income earner atm
