RIGHT AWAY! I know that many people do not wish to share that they’re pregnant with friends and family right away for various reasons. They don’t yet wish to make it public. I get that. Sharing with your Doc is not public sharing! Of course, we’re held to doctor-patient confidentiality!
Knowing a patient is pregnant helps us tailor our care to your specific needs. Initially, the care does not typically change that much, as the biomechanics of adjustments and spinal correction remain the same for the early stages. But in later stages, hormones change and the force required to make an adjustment changes quite a bit.
Also, you need to make sure you’re not X-rayed at any point in pregnancy except in extreme emergencies.
