What do these symptoms mean?

Danielle • 11 days late for AF, feeling anxious!
So had my period 2nd while the 7th or this month, I have normal periods, always have. Ovulated and had regular sex as TTC #1. Due on my AF again on the 30th but had slight pink spotting earlier today, only seen once but never before and not since. Had a serious increase in appetite, feeling sick and very emotional for past week or so. Help? Please any advice would be grateful
