Stopping for a few days

Hello everyone I have a quick question and I just wanna know if anyone can help me with this situation. I’ve been on Prozac for about two months now my dose was increased from 20 mg to mg40 for 2 weeks now . So does anyone know if it’s okay if I stop taking my meds for 3 to 4 days because I simply cannot afford to buy new ones and I’m too broke to talk to a doctor about it so I just wanna know if it could any harm or mess things up for me.
