It sounds as though you can wait. It's normal to get new moles until you're 40 or 50. The moles you describe sound like normal moles to me. By all means show them to a dermatologist when you have your appointment. If you haven't checked photos on-line, look at MelanomaNet at www.aad.org. Unless you think that your moles look like the pictures of melanoma--and I doubt you will--you should be fine to wait for your appointment. Otherwise, you can ask your general doctor to have a look sooner, if you're anxious.
Best.
