!! Help much appreciated!

Okay so I have had unprotected sex which I reget ahah so the last time I had it was oct 19 then I got my period on the 22 I believe I just know it was a day early. I was red some clump and bright red when I wiped the first day I got it , I was working and it actually drippee down my leg. So it was good amount of blood.

Now I know that I can't be pregnant

But now I'm just over thinking and going crazy I look at my breasts in the mirror and I'm like " have they gotten bigger?" Or that the aroela looks larger. In my opinion I think there puffy, but I'm also in my fertile cycle if that helps !

I never saw my breasts in a daily basis so I'm not sure what I'm worrying about

I jusr need some reassurance now that I'm okay just really worried

I feel cramps and stuff but it's probs from me stressing

And atm I feel fine
