Having issues with farting and 💩

So basically I’m having a hard time releasing gas. I’m almost 36 weeks.

I get these pains after some short time after not letting out the gas.

Nope, I’m not holding it in.

It’s just not coming out.

When I 💩 I feel some slight pain, I guess because the gas is also being released?

I’m also getting this sharp pains what feels like to be near my ovaries and in my lower pelvic area.

This may seem silly, but could it be my new weight and just sitting on my butt? When I lay down on my sides, it’s easier to pass gas but still difficult.
