Can the OP describe her training program? You said you've been training for months. Perhaps if we saw what you were doing, we could add some suggestions.
What the C25K program offers is structure and gradual increases. Since so many have vouched for that, I'll add what I have found helpful from the program:
I love the gradual progression of going from running/walking with breaks to running nonstop.
I love the structure: 30-40 minutes 3x a week. This is good because it allows your bones, joints, heart and lungs to gradually improve.
On additional training option I found totally by accident. When I first started running, I signed up for a 10k because my friends were doing it. Although I couldn't run a 5k yet, I planned to run/walk it. The week before the event, my husband and I practiced. Then the following week we finished the race in about 90 minutes. My next training run (still on the C25K program) was only scheduled for 30 minutes and that felt SO easy... So I suggest adding distance to one run a week. That has helped me successfully run 3.1 miles.
