I am 18 years old and have a two year old daughter, I alo have a heart condition so when I was 16 having my daughter the doctor tied my tubes. Now I am two weeks late and I am getting pink spotting that is only there for about one wipe and then gone. I have gotten this twice in two weeks but never before. The first time was after sex but not the second which was a week later. Could I be pregnant? I know that I have my tubes tied but maybe because I was so young it didn't hold? I took a 1 dollar pregnancy test today and it came up negative I know those take a while though. Should I go get blood work done?

If your period is two weeks late then a hpt would usually pick up on a pregnancy at that stage.

Have you called your doctor?
