When you lose a baby and been trying but no luck

It been a really hard year for me with trying to get pregnant. When I meet my boyfriend I got pregnant fast but I don’t know what happened every time I went to the doctor to check on the baby they would say they couldn’t see the baby or they could not see baby heart beat. So they told me that it’s an A topic pregnancy and that I had to end the pregnancy. That was hardest thing for me being to me young and hearing that you have to get ride of your baby for my health reasons. I was scared still scared as I been trying for over a year lost 2 pregnancy but still trying. I just scared that I might be pregnant. I am so scared to take the test and it says yes your pregnant and I end up losing my baby. I know I should have faith and trust in my god. The fear is there
