On March 3rd and 4th I had some slight cramping and random brown discharge ("old" blood). On the 5th I started my period and had awful cramps which I remedied and then later on at night they came back. On the 6th and 7th I was still having some mild cramping. And then yesterday (the 8th) I started having some more cramping which was more severe, and when I went to the bathroom, this 3 inch long "rubbery" thing came out of me.

Now, I Googled the hell out of this. People are saying "blood clots" - it is not a clot, as I always have clots during my period, always have, I get them a lot, and they can be quite large, but this is not a clot. Others are saying "uterine lining" - I don't think this is it either, as I have looked at pictures of uterine lining and it is fleshy, like skin, and this is not what it looks like. Also, both times this happened, it looked exactly the same - 3 inches long, very dark red, round/tubular, thinner at the end, and rubbery like an eraser (yes, I touched it, lol).
I cannot see my gynecologist because I currently do not have insurance. If this happens again though, I am taking a picture of it to show to the doctor when I am able to see him. Any thoughts?
