Period came 5 days early lasted 3 days confused

Ra

My period is like clockwork. 5-7 days is normal. Yea I did have sex with hubby and he withdrew ( boo).

So period came last week unexpected. It was light. Took test yesterday-and today : negative. Feel dizzy.. tightening of stomach ( right now) . Period ended over the weekend. Sat to be exact.

Nausea. Yep.

Boobs off and on sore .

Is it a weird period? Or could it just be too early to tell?? That is if i am...
