During the past 6 months I have been trying to conceive, with no success. My period
usually lasts about 4 days with a light to moderate flow. However, recently (during
the past few months) I have been experiencing severe cramping during my period and lower back pain, as well as constant abdominal pain (not severe).
I have had a previous pregnancy 8 years ago, conceived with no difficulty and to full term with no complications. Now I am worried that I am infertile for some reason.
