Peoples opinions are so annoying

It's the middle of the week and I'm tired. I was a heavy coffee drinker before I got pregnant 3-4 cups a day. I didn't drink any coffee after I found out I was pregnant which was like torture and after I hit the 2nd trimester slowly but surely Id let myself have a cup or two a week. I really only drink it when I need it. So today is definitely one of those days I NEED a cup coffee and I went downstairs in my office to my little machine  and a woman I've never seen or spoken to before goes " are you supposed to have coffee when you're pregnant?" I was very polite and told her it was fine to have 8-12 oz a day and she goes " maybe just get the hot chocolate instead of coffee". Maybe I don't need your two cents considering I have asked a medical professional if I can have coffee and have been told it's ok. What the heck is wrong with people?!
