Help a girl out

Well I’m 6 days away from my period and before I go into this

Ive had unprotected sex. No BC and no Condoms and that’s because my boyfriend and I are trying!

But I need some help.

This last 3 days has just been abnormal for me.

I’m talking about my emotional state ( very very not like me to cry) my chin acne, my bowel movements and my boobs have been Uber sensitive and sore

I feel like I’m right in between where like this would be too far away from being period symptoms but too soon for pregnancy symptoms - am I stupid for wanting test or ask this question?

Ladies... when’s the earliest you can get pregnancy symptoms?
