weird discharge on the pill.

I have been on the nortrel 1/35 for about a month now. My GP has me skipping the white pills and just going to a new pack. 2 days ago I had a reddish discharge that wasn't my period. Then yesterday I got my period. I had cramping as usual but I had something that was very strange come out? It was like a fleshy clot. I get blood clot during my period a lot and it was nothing like that. It was light flesh toned almost white and was almost like skin. It was definitely tissue and not just discharge. I had it again this morning. This time it had a brown piece on the end too. Has anyone ever had this or know what it might be?
