I went to the hospital 2 days ago due to sharp pains on my side and it went to my lower back. They said it was viral syndrome. This morning when I urined a piece of tissue came out and I have a picture...

Did anyone ever do a pregnancy test ? That would have been first thing to check ?

Also you do not go to hospital for this, you go to doctor, or clinic. If you are shot or in a car wreck you to to a hospital

We can't tell you if you were ever pregnant. Determining pregnancy requires a pregnancy test, either with urine, blood or an ultrasound in later pregnancy. No one online will ever be able to tell you if you are pregnant, or were pregnant and miscarried. It's not possible to diagnose this online, no matter how many times you ask.
