I took a test this morning and it came back positive. According to the app my due date is Dec 31st. It said I was 4 weeks and 5 days. Going back that far I feel like that is inaccurate.  I got my period right after that.  I believe it's been 3 weeks (1st week of April). But anyways since its still early I was just wondering if I can get some advise as to what I can and can not eat/drink this early on?  My Dr appointment is in a week and a half. Also I am diabetic so I really need to watch my sugar. My concern this early on is coffee. That is my life saver for keeping me awake especially on my morning commute to work. Please help!
