Early symptoms?

Im spotting on and off and last night i went to bed at my normal time, woke up just now and i feel EXHAUSTED. i even had my coffee already! Im so irritable too like i have no patience for anything right now and my anxiety is THROUGH THE ROOF the last few days to the point where i dont even wasnt to be around people! So basically, i feel drained, irritable, and my anxiety level went up (over nothing im a stay at home mom so no work stress or anything like that). Im honestly not even sure when i ovulated but my last period began on jan 1st so im on cd 17 today.
