Could I possibly be pregnant?

So I had sex the day before my peak ovulation day and the day of. My period is due on the 17th and I’m about 7 DPO.

I guess it’s too early to test because I haven’t even missed my period but, is it possible to have period symptoms leading up to your period but still be pregnant?

I have been having mild- what I believe to be- period cramps & two days ago I was having pretty bad cramps and felt this weird tingling sensation happening in my lower abdomen/ uterus area & it really freaked me out, felt alien like lol. Could it have been gas? Idk I’m anxious
