upset

I found out I was pregnant on Janurary 15 and I was 12dpo when I took a test it was a faint line. Then now My family be saying that they don't think that I'm pregnant and I was like how I cannot be pregnant if I went to an appointment the same day when I took the test  so they could tell me if i really am pregnant. First the doctor said I wasn't pregnant  then I was like I took a pregnancy test and there was a faint line then the doctor said that he's gonna take some blood out of me and then he said it's positive and he showed a pregnancy test and it was 2 test positive. I haven't went for my 1st appointment for a check out for the baby. I'm just scared because I really want a baby but my family be saying that they don't think I'm pregnant plus my period haven't come a month. My family is wrong what there saying saying right?? 😕
