How early is too early for symptoms?

My husband and I had unprotected sex little under a week ago. my periods are pretty irregular so its hard to predict “ovulation” so usually when I input my period it changes the date I was supposed to ovulate on the app.

It’s not been a long time I know, but I’ve started breaking out like crazy on my face, my stomach has been super bubbly the last few days, emotional like crazy, hungry all the time, and I am super fatigued and always sleepy, really bad skin dryness (especially on my face) and it’s really confusing to me.

Basically period symptoms but x1000000 and I’ve never had period symptoms this strong. And my period estimation is probably within a week-2weeks from now.

Has anyone had any symptoms from implantation? We had unprotected sex early last month but then I got my period so I doubt it would’ve gone back that far.

But this week was the only time we had unprotected sex since then. Is it possible implantation could cause these kinda symptoms?
