Your probably ok, really. All those muscles are changing down there and some things just feel different. Just mention it to your Dr when you see him. If you have any bleeding, call him.
My next appointment is on the 7th, i hate having to wait
I would see your Dr. It could be very normal, but it's also a symptom of an infection. You should not need to really push to have a bowel movement, it should be a relaxed squeeze. Try drinking more water and eating fiber rich foods. You could just be straining your soft muscles which is normal, but try to help yourself not do. If you have this more often for a few days, check with your Dr that you don't have an infection in your intestines.Hope that helps
