Can I eat this?......?

I'm 9 weeks pregnant tomorrow and have REALLY been struggling with my food this last week. I've lost half a stone since I fell pregnant, which my midwife said is normal in the early stages. I haven't been able to eat much but have been trying my best. This might sound like a silly question, but can I eat Ambrosia devon custard (It doesn't mention eggs in the ingredients for the custard) and Heinz Sticky toffee pudding? (Says it may contain eggs). I have been feeling like having something sweet for the past half an hour and just want to know before this wears off and I feel ill again. I've not fancied or had anything sweet or puddingy for weeks and weeks now due to me feeling so sick.
