Feeling disrespected and belittled

So I’m 24 weeks along now and finally showing enough that patients at my work have started noticing I am pregnant. I work in a physical therapy clinic and today had to have a conversation with a patient who has been fairly non compliant at every session but today lied about having completed his entire treatment and walked in to see our massage therapist without being call back by the staff as is the standard. I explained to him that at future appts he needed to await direction from the staff prior to going into massage because he had not concluded his exercises and there may have been other patients waiting for the massage therapist. He flipped out and raised his voice telling me that his time is valuable and he refuses to wait when all he is here for is massage and that he already told his PT that this was his plan. I kindly explained again that I also spoke with his provider and he had not completed the exercises they discussed and that either way it was not appropriate to just walk into the treatment room of the massage therapist without being called. He proceeded to talk over me and try to mansplain/intimidate me into backing down and when I continued to explain to him that his behavior was inappropriate he called over the male PT and told him in front of me and the other staff that I am just being dramatic and hysterical because I am hormonal and pregnant. I walked away. I spent the rest of the day making light of the situation because showing that it upset me would only substantiate his idiotic remark. Thankfully my boss is awesome and has my back on the situation and the patient will no longer be seen with us but nonetheless I am left feeling both belittled and enraged.
