mucus plug??

So this isn't a very good picture, but my back camera doesn't work.. Anyways, if you can't tell it's like a clear yellow maybe light green? I'm 36w2d and not very sure if this is my mucus plug? About 5 weeks ago I lost some mucus with blood in it and went to the hospital but they told me it would grow back... should I be worried or anything? I was in the hospital for contractions two days ago  and they told me that I was having false labor or whatever it's called.. Should I call my dr or let things go on their own? I've been having Braxton hicks all day but I'm a ftm so I'm not really sure of the difference. Does losing my mucus plug (if this is it) this time mean that labor will be coming soon?
