Deeksha

Hi guys i am 12 weeks i am not finding any symptom of pregnancy neither my belly is turning up i met my doctor last when i was 10 weeks she said everything is good. No need to worry but this is getting a little onto my nerves and i am a little skinny. My next meet up is after 3 days is it a problem to worry. And no cramping or spotting felt everything is going as it was going earlier. Please can anyone suggest me in this
