Anyone experience this?

I'm 39 weeks today and got my membranes swept yesterday at my doctors apt. I got a little bit of cramps after and brownish/pink discharge. The mucus discharge has continued I've been getting it off and on since yesterday and clumps keep coming out that are browish/pink mucus. I was sure I lost my mucus plug awhile ago but these clumps keep coming. Anyone else? Also did anyone else get their membranes swept? Was it affective ?
