Horrible pressure but can't poop

KK • A busy momma of 4 👶🏼. who works hard 💉. Is a travel feen. loves ☕️ , 💪🏼 🏋🏼‍♀️and her 2 😻. While loosing sleep to spend endless hours on glow. 💁🏼‍♀️

Is this happening to anyone else? This started last night around midnight and has lasted throughout today. Ive had horrible pressure in my butt and I'm very nauseous, it's kinda feels like I have to poop but I've tried and I can't. It's so weird and I know for a fact I'm not constipated. I feel relief if I lay down but as soon as I stand up or walk around it's very uncomfortable. Im 35.3 btw.
