Thank you.. ive been.cramping, but nothing is happening, I've never been this late with my period... its really weird. But thanks for your advice
No, it is not a pregnancy symptom. It could be a pulled muscle, or it could be something serious. You should see your doctor for a pregnancy blood test, and to discuss the chest pain. I would go as soon as possible. Not ER urgent, but I would say try to make an appointment as soon as possible this week...however, if the chest pain gets worse and/or is accompanied by shortness of breath, severe dizziness, or confusion...go to the ER (have someone drive you) or call 911 immediately.
