I asked him, he said it was my mucus plug. It's different for everyone. It wasn't huge just bigger than I thought it would be.
It should not be green.... it is usually clear, slightly discolored, or has blood mixed it, but I have honestly never heard of green and large, and it is somthing you normally wipe away, not something you notice floating in a toilet, I mean I guess we could read up about it, but I have had 3 kids already and this is my 4th and I have never heard of green discharge or mucus plug. Could ask your doctor too, I suppose.
It CAN probably be your mucus plug. Im thinking I lost my mucus plug around 32wks or so also cause I did see this green like thingy but didn't see it clearly enough since I already flushed.
