I am 21 yrs old and had my first child 7 months ago. I'm not breastfeeding so my periods have been coming at their regular time each month... except now. I am 5 weeks late and have taken 5 home pregnancy tests all of which came back negative. I am showing some signs of pregnancy also. Could I be pregnant even with the 5 negative tests?

Not the norm, but it is possible that a pregnancy isn't being picked up yet on the urine tests. I would either wait and see if a second period is missed, they can just be off now and then, or go to the doctor's and ask about having a blood test done.

Usually by the fifth week you have a high level of pregnancy hormones that a regular at home pregnancy test can pick up, so just wait it out and see what happens.
