What Causes Discharge Of Skin Like Substance Through The Vagina?

On the second day of my period I found something very strange on my sanitary towel. It gave me such a fright and I've been worrying since.



It's difficult to describe - it was about 7cm long, had the texture and look of skin, although slightly more rubbery, and in the middle it was much thicker, like folds of skin with an opening (kind of like a flower bud I suppose.) At both ends it thinned out and had blood on it. I'd only lost a tiny bit of blood during the 1st and 2nd day of my period, but the towel was full of blood when I discovered this thing, and I've hardly lost any blood since. It was yesterday when I discovered it.



I'm too scared to go to the doctors (I suffer with panic attacks) - but I'm also scared that something has fallen out of me that shouldn't have.



I started taking the pill (Yazmin) one month ago. This was my first period since starting taking it - and I didn't have a period last month because I started the pill one week before my period was due. I'm definitely not pregnant.
