8 Weeks !!

Yesterday, was my 8 week mark. I swear every Saturday feels like a holiday ! 8 days from now is my first appointment Lord knows I just want to hear a heartbeat. I'm so anxious and excited at the same time. I've just had the normal symptoms, occasional aching but from what I've read it's from the uterus expanding. I have not seen any spotting or experienced anything not normal. Can't stress enough how badly I want to hear a heartbeat but I'm doing my best to wait patiently. I struggle with eating healthy. I have been but sticking to it is what's hard for me. I drink water and mainly eat bananas for snacks. What are some good foods to eat while pregnant ?
