First baby

Well I'm pregnant with my first baby and everything is going well so far I get more signs everyday which is a good indicator that my levels are rising in still nervous about having a miscarriage though it scares me I have never been pregnant before like ever plus I told my mom that I'm pregnant and it's like she doesn't believe me she says hpt aren't accurate and give false positives of course I did research and found that it's nearly impossible to get one unless you take certain drugs and my line on the test came up not even in 30 seconds it's very dark but light but it's definitely there
