Ugh again help?

Anyone having a light spotting? I'm 19wks & 5d it started last week on& off I already went to the hospital and my OBGYN they couldn't figure out what was wrong they checked the baby he was 100% healthy anyone else experiencing this or has? Cervix is closed haven't had any sex. Doctors say its possibly cause I'm on my feet a lot but I rest so much my boyfriend does almost everything. Just wanna see who else is having this as well? Also been having Braxton hicks got scared but like I said my baby is 100% healthy and fine.
