I have been spotting for 3 weeks and period hasnt come. Am I pregnant?

Posted by Samantha L.

I have been having a stressful few months with work and relationships and have lost 2 stones of weight in the space of 3 months. I experinced spotting a week after my normal period. This has continued for 3 weeks till my period was due again. I am getting the cramping feeling but am still only bleeding extremely lightly. I am on the combined pill and am sexually active. I did miss one pill in my packet, but waited 7 days before having sex to insure I was protected. Could I be pregnant?? Am very concerned. I took a test a week ago before period and it was negative. Should I do another one?
