Early pregnancy symptoms?

Does this sound like early pregnancy symptoms or period symptoms.
The two are so closely related it seems.

I would be 4 weeks now, my period is due in 2 days.
I know I should just wait but I’m nervous.

So I’ve been feeling nauseous for the past week maybe, weird feelings in tummy and really bloated, like I look 4 months pregnant I’m so bloated – my breasts were sore about 2 weeks ago, but are not anymore but feel bloated also, which I know is a sign of period – so how do you tell the difference?
I have a slight cough and sore throat which I’m told can also be an early sign, I could be pregnant but it’s very slim given time frame and when I ovulate.

Anyone have any thoughts?
I definitely feel sick, but that could be nerves?
