Gelatinous black gunk on bathroom faucet

Sarah
Crap! Why do all the things keep cropping up to worry me now that I'm pregnant? We just found out last week and I am about 5 weeks along. We are staying at my in-laws' shore home this weekend in southern Maryland for Memorial Day. Last night as I was brushing my teeth, I noticed a black, gelatinous gunk dripping from the faucet after I turned it off. I've been brushing my teeth and washing my face with that water all weekend! 😬 Any advice on how freaked out I should be that this will harm the pregnancy in any way?
