Discomfort in stomach

Hey, feel a bit embarrassed but i was wondering if this is normal and if anyone else has experienced similar issues… Im 38 weeks tomorrow and this past week i have started showing signs that labour isnt far away - mucus plug has been coming away, bump has dropped, baby is low already, period like cramping below my bump, alot of sore pressure down below, feeling sick at times etc. But the embarrassing thing for me is i constantly feel like i constantly feel like i need my bowels to move, majority of the time its a success but other times i get to the toilet, the sensation goes..
