How can i know if i am pregnant or not defore i'd be able to make the test? is there symptomps before my period is late?

Some do, some don't: Some women may experience early symptoms such as mild spotting (implantation bleeding), cramping, nausea, and possible some clear/whistish vaginal discharge, but many don't feel any until after missing a couple of periods. Blood test can show very early on, but a home pt typically shows a few days after late period--if pregnant. Sorry for a long-winded answer, but this is how it is. Good luck.

You cannot: There is no symptom that is consistent or reliable enough to tell, it's all just guessing. You just have to wait until you can test.
