Anybody else has this situation?

I’m a healthy size 12/14, Just within BMI range and trying for only 3 months but my GP had the audacity to tell me to ‘prepare for difficulty’ because of my weight??

What??! Anybody else been told this? And also please put my mind at ease if you’re a nice healthy size 12/14 and have wonderful babies 💙 I only went to get my blood taken and iron discussed. Now I’m fuming and worrying!
