My cycle is 12 days late as of today (03/08/13). On the day before my period was expected I used a tampon because I felt as if my cycle was going to start (slight crams/ period flow feeling). I bled just a little enough to wipe and notice but not enough to reach my underwear. I had cramps and period flow feeling the whole time my cycle was expected but it never started. That week I also had frequent urination about every hour sometimes twice an hour. I took a cheap pregnancy test the day of my missed period and also a week later both negatives. His morning my urine had a slight bold smell to it. Could I be pregnant still? If not what do you think is wrong?

12 days is a long time to be late.

Ask you doctor for a blood test to see if you're pregnant. It will give you a more definite answer. It's not uncommon to have bad readings on take home tests as many things can effect their accuracy, such as not peeing on it long enough or too much, etc.
