Well, if she became pregnant when you said, her time is close. Let's leave her be for another 24 hours. She will surely have her kittens soon. She is huge in your picture. I cannot imagine she will not birth them soon.
she only sleeps and drinks takes her 2 days to finis half her food bowl so it takes 4-5 days to finish her food bowlIf she's 9 weeks and 5 days she's about 68-69 days? Still not unusual. But if she's appeared to begin labor and then stop, wouldn't hurt to check in with your vet.
