Hellllp

I think I am around 6 or 7 weeks pregnant that is all according to the last time I had a period. I have a mw appointment on the 21st but for e past 2 weeks I have been feeling movement in my tummy. This is my 3rd pregnancy I'm not sure if I am Further along but it doesn't add up with me having periods my fam are saying my belly popped right out and it has but I was just thinking it's bloat and Xmas eating. I have been layed in bed tonight and really feeling something am I going mad???? I even felt it when my hand was over my stomach so strange. Is it wind?????? I think I'm going to try contact the midwife tomorrow I just don't want her to think I'm crazy
