I'm 7 weeks a 2 days pregnant, I have been to the hospital for dehydration once already because my morning sickness was so bad an I couldn't keep anything down so I stayed in the hospital all day an night to get fluids in to my system baby was perfect had a strong heartbeat, but now I'm having trouble pooping I haven't pooped in a week, tonight I've finally got to poop an it's so painful i cry every time I try to squeeze something out, like the pain is unbearable 😭 anyone else experiencing this?
