Any advice about pooping would be great please...

I'm coming up to my 13th week, for about 3 weeks now I've had massive trouble trying to go for a number two... The feeling is there, I have really bad flatulence, like sickly smelly bad... Everytime I try to poop it feels like a water drop bubbles but nothing comes, when I wipe the tissue is covered in runny poop, I have to wipe 5 or 6 times to make sure it's clean. What can I do to make myself poop??? 😣😣😣 I smell so bad it's embarrasing when I have to pass wind, which is a lot recently...
