Hello, The first day of my last period was the 16th July, i was due on Augest the 12th so i'm bout 12days late. What are the chances of me being pregnant? I am doing a test later hopefully but i don't get paid till next week and i'm going to be getting only a cheap one, i think they are called "predictor". If i am roughly how much HCG would there be to show on a test, will there be enough?? Can someone tell me if these are reliable and what are my chances if i am pregnant to show up on these?
