I had the worse cramps before and on my period. This time I bleed for a day the next day there was no blood almost all that day,then there was a little darker blood torwards the end of the day. But when I was in the bathroom and whipped there was like tissues. Stringy almost. What does that mean? Does everyone have a tissue discharge?

To have some "membrane" or tissue is normal, you have to consider that it's your inner uterine lining shedding. Have you recently switched birth control? Had a baby? Anything of the like? Remember to call the Doc if you are having large amounts of clots (tissue) or excess amounts of bleeding.

I have had blood clots before, but I have never seen tissue ever. Like 2 good picese of it. It freaked me out a little. So you don't think I could have been pregnant? I have never had a baby and I'm not on because.

It could be a MC, but it depends on the amount of blood... with a MC you will bleed heavily in a short amount of time, (example is soaking 3 pads in less than an hour)

If you are concerned about the tissue, call your doctor, you may not have to be seen, just ask to talk to a nurse.
