worried.. update

I decided to make an appointment in a stand alone ultrasound clinic and was able to see my baby.. everything is fine so blessed to be ale to see my precious baby. Thank you for all your kind words 😊.....
I am concern and am hoping someone can tell me if it's normal. I have a doctors appointment on Tuesday but these thoughts are killing me. I drank coffee today like I've been doing for a couple of days, I usually drink some and the next couple of days I don't, well today I did and was very jittery. I felt like i had too much energy and I never feel that way, I am 16 weeks pregnant. Today I noticed the tenderness in my boobs went away and it is just making me worrie, ive had a missed miscarriage before and that's how I felt, my pregnancy symptoms just went away. I never rally had any other pregnancy symptoms, no nausea just tiredness. I am just very worried. Has somebody had that happened to them, donsore breast just diasappeaeed? Thank you if you read all my message.
