December 8th was the last day of my last period. December 8th I also got a tampon stuck very far up and had to go to the emergency room to get it removed. Its Jan 19th and my period hasn't come! Took pregnancy test, Negative, Twice.

It could be that you're just having an off month. It happens to all of us. It could also be that it's just too early to test.

Wait until your next period is due. If you skip that one as well then try another pregnancy test. Make sure to use first morning urine for accuracy.

Good luck.

Take a blood test.. They are more acc.
