Constipated and nothing is working

So it’s been 7 days since I last went for a poop and nothing is working, i’ve tried 3 different stool softeners (Califig, fibogel and dulcosoft) that normally make me go and prune juice but nothing is working

I’m 16, I also drink more than 2litres of water and eat healthy food that’s full of fibre

I’m worrying too as what if I don’t go for a few more days, I feel bloated and I have 7 DAYS OF FOOD in me

Please give me tips in anyway you can and I’ve also got school this week 😭😭
