The doctor will have the answer. Personally I wouldn't wait if I fear somethings wrong with my unborn child. If you are concerned but feel you can wait you could try a quick 'yes or no' tarot reading where you pull one card. You could also try using a pendulum. Third option would be to meditate and 'sense' if anything is wrong with the baby. But above all I would see a doctor if I had any concerns. Hope everything worked out alright.
