New fear

So call me crazy, but I knew I was pregnant from practically day 1. I could just feel it in my gut that I wasn’t “alone” in this body anymore 😂 now I don’t feel a connection I guess you could say.. I kinda feel empty in a way. In the beginning I was having constant lower back pain as well as a few other symptoms, but now that I am 7 weeks that only symptoms that come to mind are my sore breasts and increased hunger. First baby appt isn’t until Feb. 13th when I am 8w3d. Should I be worried about my baby??
