Whats Goin On Mother Nature?? HELP‼️

my period is late but im still havin pms symptoms. i had one child already so i know when im pregnant, i knew i was pregnant the day after he was conceived so i know the feeling, but this one is different. its not the same feeling. ive been stressed lately so could that be just it? im bloated, little side cramps, and having the same amount of bowel movements like i would have if my period came. im soo confused and i dont need another one. can stress make me miss my period and how do i induce it

to come. i had a missed period before but that was when i was younger. can it be happening again?
