Sex time

Hey so I just had a question ladies... could sex in the first couple of weeks of pregnancy cause miscarriage... or hurt the baby ? I have 2 kids & with them I didn’t find out I was pregnant until like 8 weeks plus that was years ago but they where both full term no issues but this time around baby #3 I find out I’m only 5 weeks but for some reason I’m just so scared and really nervous something will go wrong my faith in god is so strong but I do worry a lot now
