Damp panties smells like chlorine or bleach. Not the same look or smell as my usual discharge.

Not sure if I am just being paranoid or crazy but I do typically have a white creamy discharge with a slight smell to it during this pregnancy. But I just went to the restroom and noticed my panties were damp and an absence of my typical discharge so I smelled it (I know, gross right) and it smelled like chlorine or bleach. I'm trying not to think too much into it but I googled what I described and it points to leaking amniotic fluid. Out of my 5 current children, 3 were premature (30 weeks, 34 weeks, 36 weeks) all due to placental abruption. So my nerves are rattled. I have been given 2 due dates......one puts me at 26 weeks and one puts me at 27 weeks.
