Poop question lol

I have had somewhat loose stool all day today and then I eat lunch and not I feel like I gotta go and I can't .. Constipation at its finest. Well what I'm worried about is when I feel like this it makes me not want to eat. Well I am being induced at 5 am tomorrow morning so I know I need to eat dinner but more importantly I'd like to have a good still before I go tomorrow bc of what I'll go through tomorrow.. Oh the joys of being pregnant. Any advice ?!
