Could i possibly be pregnant?

Okay so, i only had sex 2 times before i got my period but it was a week before and around my ovulation date.

I felt nauseous, sore breasts, back pain, crampy whatever.

I also been eating, ALOT like i could eat a whole

mea then 5 minutes later eat another whole meal. Which i never get like that before a period, i usually hate eating especially on my period because im so crampy but nope im still eating so much lol

I got my period on saturday and didnt think nothing of it, until on the third day i started to notice it stopping?? and today on the forth day literally no blood at all.

Ive NEVER had a period stop before 7 days, ive always had 7 day cycles since when i first got my period when i was younger & even last period was 7 days too.

Just curious if this happened to anyone and been pregnant?

Ive heard people getting pregnant and still getting their periods and it stopping halfway but im not sure if thats the case for me and im just hella confused.
