Feeling sad 6w6d

Is anyone else just feeling sad overall?

My husband and I were planning to start trying this month and I just kind of had this feeling that it would take a long time and be difficult but we had a little surprise and would up becoming pregnant the month before we planned to start trying. I feel so blessed but can’t shake this feeling of just being sad and I hate it. I also just have this overwhelming feeling that something is wrong and I’m counting the days to my first ob appointment.

Anyone feeling the same way?
