my body rejected a enema and i am so scared

i have not pooped in 3 days and i know that’s not good cause i have suffered with constipation my whole life and have gone with more then a week with out pooping and i am so terrified that this is happening again.

i inserted a enema and my body rejected it within 60 seconds i went to the toilet and pushed out the enema liquid but not the poop. and it hurt i have also taken a laxatives dulcolax drops in water 5 hours ago before i did the enema and it did not do anything.

it feels so exhausting to push for so long when nothing is coming out and i can’t push anymore! and yes i have ate fiber and yes i drank a lot of water

UPDATE AFTER 4 DAYS OF CONSIPATION I DID IT: i was having a warm shower and felt this urge to do one and it’s now or never AND I PUSHED AND WAS BREATHING SO HARD LIKE IT WAS CHILDBIRTH N I DID IT!!!
