<human>: Background: I'm a 2nd year pharmacy student working in a retail pharmacy as an intern. I also have never thought I would be the guy who assumes a women was pregnant because of her size..

This happened a couple of weeks ago. A patient comes in with her young daughter late in my shift 6 hours in or so to order a prescription and also pick a sudafed (a decongestant that is sold behind the counter because people like to make meth out of it, also it is has only really been proven safe in the 1st trimester of pregnancy). Now when I look at her med profile I thought that I recognize her as a patient who had come in a few weeks earlier who was diagnosed with gestational Diabetes (a type of diabetes that women get when they become pregnant). Now this women was not thin but not fat either, was of child-bearing age, and I thought I remembered her, and on top of all this it was 8:30 at night and I was tired from a full day of classes and work. So when the women asked to purchase Sudafed I, out of genuine concern I asked this women what trimester she was in (obviously I should have asked if she was pregnant first but for all the reasons above this thought did not even cross my mind). After I asked this she looked at me with the most defeated look in her eyes and asked, "Did you just ask what trimester I was in? I am in no trimester.." Then turns to her young daughter and says, "He thinks I'm pregnant.." 
At this point I am mortified about what I have just done. I start apologizing profusely, quickly finished up with sudafed checkout (the whole time she maintained the look of defeat the entire time)  and then I retreated to the back of the pharmacy to wallow in shame over how rude I was. Now I see her all the time when she comes into the pharmacy and I avoid eye contact.

Can you condense the text into three sentences or less?
<bot>: thought I recognized a women as a pregnant pateint, asked her what trimester she was in, she wasn't pregnant and I ruined her day.
