is there a way to know if you cant have babies? URGENT

Depending on your age and how long you have been trying to conceive, doctors will perform different tests. Some you will need to undergo, and some your partner will need to undergo. On average it can take a "normal" healthy couple 1-18 months to conceive if actively trying to have a baby.

i'd say go to the doctors. i actually just found out i don't have a uterus. so, i can't have babies :[

Hello there,

Unfortunately you need to consult your doctor about this matter because you can’t really know how fertile you are until you start trying to conceive. My best friend is married to her husband for about five years and three years ago they have started to work on the baby. Unfortunately they are still trying to get one.

They went to the doctor and they have done all the tests the needed and in the end doctor has told them that absolutely everything is fine and that physically there is nothing preventing them to have baby.  But unfortunately they are still working on that so consult your doctor and the only way to find out is to start working on it.
