I neeeed to poo!!!!

I’m suffering from awful constipation at the moment. I haven’t pooed properly for about 4-5 days. I’m so uncomfortable and getting really bad stomach pains. I need to go but literally can’t get anything out. I’ve drank loads of water and eaten weatabix with prunes this morning. I’ve only got senna tablets in the house but can’t take those until bedtime.

What foods/drink can people suggest please?! I need to poo!!!
