Hello, wow ten days late that sure could be a sign of pregnancy. However, since all the hpt's that you've taken have come out negative you may not be. There is always a chance they could be wrong, or maybe the hcg levels are not yet high enough to show a positive. Another big factor that can cause a period to be delayed is stress. Are you under alot of stress? Well I hope you get the results you are hoping for. :-)

Are you having any other symptoms of pregnancy?

I have been having a few symptoms. I have heartburn all the time, I have been feeling like I have to urinate more often, I have been feeling tired more often, constipation, and my nipples and around the have gotten a bit darker. Also increased vaginal discharge. I dont know if this is a sign or not but a blue coloration around the vagina. So I guess im having more than a few symptoms....
