Constipation?

I’m sorry this is tmi but I have been super constipated. I have only had one bowed movement in 2 weeks and it was a small, hard dry stool. I’ve tried squatting over the toilet (someone told me that would help), drinking water, eating more veggies, miralax, but nothing is working. I constantly feel like I need to go to the restroom but when I push nothing happens. When should I see a doctor?
