TMI... like really TMI

Okay I've added this anonymously because it's so embarrassing😩 I'm 19 weeks with twin and have been really constipated, I've tried everything to help me go but nothing works, this isn't my first pregnancy( I never went through this with my first). But any who Im already very big on size with these twins, I look like a 6/7 month pregnant women, but yh to get to the point. I was tryna go poop, but the constipation pain was crazy to the point it had me in tears, but every time it came and I tried to push I felt like I was going to vomit and loe and behold, I vomited, my partner comes running in to me pooping like a mad women and vomiting up my dinner all at the same time 😩 embarrassing doesn't even come close. Has any other moms gone through this. And have you got any suggestions on what can help me poop more easily, I've tried all the veg and fruit you could think of
