Over reacting?

I had my last period on August 12th, had light spitting around September 16...which I thought was the start of my period...but then nothing. The last two weeks I have been just...off. I have been puky, runny nose, short of breath and just feeling exhausted and just over everything, ya know. My periods range from being regular to irregular so its hard for me to know. Also past couple mornings been waking up with a,watery type discharge, no smell or anything...just kind of like w.t.f.

Thanks😁
