Your beer is still fermenting. If it's at about 20*C it will be fine. Someone said US-05 takes a long time, some yeasts do that, others don't and can be finished in a few days. Basically it will be finished when its finished. Your OG at 1.047 has only had a small impact on the time it is taking relative to a slightly lower SG say 1.042. My advice is to forget all about it for another 3/4 days then retest the SG if its still going down leave it longer. It won't do it any harm to leave it in the FV. But I suggest you back off adding your hops until the SG has bottomed out. And in the meantime try to keep the lid on.
