I have my doct app on thur do i tell her im having early contractions at 28 weeks . ?? or do i ask her ?

Absolutely tell her, but they may be what's call "Braxton-Hicks contractions" which are just practice contractions that start in the second trimester. If they tend to get better once you're moving around, they're irregular, or go away, then they are most likely BH contractions.
