Hi, I'm new to all of this and am so confused. I am now 16 days late and have taken 2 hpt's and one urine at a planned parenthood. All were negative but I just can't shake the feeling that I'm pregnant. I'm 20 yrs old and a little worried but I'm not overly worried! I know that can cause your body to do weird things. I didn't even realize I was late until almost a week later when I looked at the calendar. Any advice would be greatly appreciated! Thanks!
