TTC -pregnancy symptom?

So AF was supposed to start a months ago give it take (I have irregular AF) 

I took a test the day it was due and got a BFN and also 4 days late and still BFN 

I'm now on cycle day like 47 and still no AF 

I thoughttttt it could just be a weird month and we were waiting to BD again until AF shows and just start over again but today I just got out of the shower and we realized my ankles and feet are swollen?? I just spent the weekend with a very pregnant friend and they are doing the exact same thingas hers? Could this be a possible PG symptom?! Or am I just getting too excited and should be running to a doc for whatever causes swollen feet 😂 any advice??
