Please help

Hello, I (23M) am constipated. I haven’t had a solid poop in close to a week, just pebbles that i have to strain to force out. Yesterday I drank 1 Miralax packet in water and today, I was sitting on my toilet feeling intense abdominal pain, thought i was going to be able to go but i just couldnt, it felt like it was poking out of me but would not come any further and drop out. When i would stand up, what looked like poop water would drip out onto my legs, so after about an hour or so of sitting on the toilet i gave up and got in the shower, paced around in there for like 10 minutes and i believe the poop that was sticking out went back in (not sure if thats a problem or not would love some insight on that). I’m pretty freaked out since I have never experienced something like this before, and am not sure if i should seek medical attention or not. If anyone could offer advice or anything i would deeply appreciate it EDIT: forgot to add, I have been eating pretty regularly this whole time, and my diet isn’t the best. Wanted to include that context
