In general, doctors don’t recommend strength training while pregnant because women's joints loosen during pregnancy (in preparation for birth). However, in your case, your doctor may feel comfortable with you continuing to lift weights throughout the pregnancy since you have been doing so already. If that’s the case, just keep in mind that you should simply try to maintain - not progress - during this time, and that around the trimester and directly following delivery, you will likely have to significantly decrease the intensity and/or take a break from strength training. Keep your doctor informed of your activities and always listen to your body.
