Concerned

So I havent had my last period until July 7th , up until August 8th I’ve been getting cramps here and there in the vagina as well as stomach . Sex was on the 15 , 19 , 31, each with condoms , the only time I didnt use a condom with my partner was (july 6th day before period ) & he had pulled out way before coming and jerked off . SOOO I’ve been stressing as well really bad for about two weeks just from some overwhelming things thats been happening and I’m not sure if I should like Idk get worried that it might be pregnancy because I’ve seen everyone else said they’ve been spotting (but i have not ) and such but I’m feeling normal as if my period is coming ....i always am gassy , and cramping days before .

Anyone can maybe guide me or help ?

Period was supposed to start today but hadn’t and the cramps has increased over night in the vagina and stomach while at school too
