Anxious wait to KKH

Hi.. first timer here on this app. I have been trying to conceive for 4years and this month I missed my period and used the pregnancy test kit for 3 times last week and it was positive. I have an appointment at kkh this 21st but in the mean time Im trying not to expect too much coz I'm afraid of disappointment. The app said that I'm 5weeks and 4days. I have sore breasts and cramps like period cramps. Is this normal? What do I eat during this period? #advicepls
