Anatomy appointment - worried 😞😞😞

I'm sorry this might be a little long, please bear with me...

I had my anatomy appointment today at 19w 5d. Everything went fine - the only problem the tech was having was that she couldn't get him in the right position for the pictures of the heart they needed. A short backstory, I am currently on 25mg of Zoloft and feel immense guilt about it every single day. I am so afraid of hurting my baby.

So she finally gets what she needs and let out a sigh of relief (which worried me) but I stupidly didn't ask. She told us at the beginning that we would be meeting with the doctor so that wasn't concerning. We met with him and he told us that everything was measuring as it should. He then asked if we had a family history of heart disease or cleft palate and said that he asks everyone that and it's not a result of what they saw on the screen but I don't believe him. I told him about my medication and said that I would have to be scheduled for another ultrasound as a precaution once the heart is bigger - mind you, I am already scheduled for this ultrasound on the 15th, as it was scheduled when I was 8 weeks pregnant because of the medication. He then goes on to tell me that everything looked fine but they just needed to wait until the heart was bigger, but he could tell that I was bothered. He asked me what was wrong and I told him I'm concerned about the heart, and he said "why? I'm not"

I don't know if it comes from the guilt that I feel but I don't feel like this appointment went well at all. I feel like they saw something that they're not telling me, even though I know they're not supposed to do that, and what would they gain? Has this or a similar situation happened to anyone? Has anyone onSSRIs had to have an extra ultrasound for the heart? Or did I really fuck this up? 😞😞😞😞
