See your doctor: Symptoms and concerns like these mandate a thorough evaluation by your doctor. Only after such an evaluation, which may include labs and radiographic examinations, can he/she let you know what's going on and how best to help you.

Neg preg test: If your pregnancy test is negative the you did not get pregnant this month. There is nothing wrong with having a light menstrual cycle. Many would trade places with you. Healthy couples with no medical issues should attempt pregnancy for one year and if unsuccessful seek an infertility specialist.
