My girlfriend keeps on asking me when am I ready for kids?

She keeps on asking me when would I be ready for a baby, I said after everything has died down (my mum had twins, her 2nd set prematurely, her mom has terminal cancer, we're going to become legal guardians to her 3 younger siblings........), and she came over about 2 hours ago, and I went to the shop, and instead of walking around with me, she went off on her own, she paid on her own too. She left 10mins ago to go see her mother, but there's a positive pregnancy test on my sink.....
