Early symptoms?

Hi ladies!

Me and my husband have unprotected sex and I'm pretty sure i was ovulating when he didn't pull out at the beginning of this month, week after my period ended.

I am extremely tired, i have cramps in my abdomin and headaches.

I usually dont get cramps or anything before my periods, so this is abnormal for me.

I should get my period in a week.

Not worried about being pregnant, just curious as to if i would experience any symptoms this early.

Thank you!
