Symptoms or something else

Hey ladies so I think what I’m having is a lot of pregnancy symptoms pretty nauseous throwing up,Boobs kinda hurt and pretty emotional for no reason always tired! And today I’ve noticed my hands being swollen my ring was like stuck on there lol

I know the only way to find out is obviously to test but I’m not totally sure it’s even possible to be pregnant because the only time me and my husband had sex (he finished in me) was 1 day before my period started,of this month in August.

Maybe TMI but The last time I got pregnant I’m guessing I ovulated while on my period because that was the last time we had sex and a few weeks later found out I was pregnant (with my 1st)

I’m just so confused any thoughts? Are these actual symptoms is it possible to be pregnant or is it not even worth testing maybe it’s just something else.Thanks ladies,in advance.
