With my first pregnancy, I was 3 or 4 days late. I took a pregnancy test, and as soon as it turned positive, my husband was on the phone, announcing to everybody. I was probably 4 weeks....
My mum and sister told most of my family when i was 6weeks. My pregnancy went fine tho and nothing went wrong. im sure ur pregnancy will be fine too and try not to worry about things going wrong bcus if u do; stress affects you and ur baby! try not to worry:) and good luck!
