Research has found that underweight women are 72 percent more likely to experience a miscarriage in the first trimester when compared to women who had healthier BMIs.

Light spotting during the early months of pregnancy is actually quite normal and does not necessarily indicate a miscarriage. Heavy bleeding, passing of blood clots or consistent bleeding is much more worrisome and is normally the first signs of a miscarriage. Most women will see a doctor or midwife when they experience any type of bleeding simply to make sure everything is okay.

Endometriosis is a very common gynecological condition affecting women in their reproductive years. Over time, accumulation of scar tissue causes adhesions and sometimes severe pain, if close to nerve fibers. When impacting the fallopian tubes, endometriosis can also negatively impact fertility and outcomes of infertility treatments.

Blocked or damaged fallopian tubes prevent eggs from getting to the uterus and sperm from getting to the egg. Leading causes include pelvic inflammatory disease, sexually transmitted diseases such as chlamydia, and previous sterilization surgery.

Some medications (e.g. phenothiazines) as well as extremes of weight loss, stress or exercise can cause this type of secondary amenorrhea. A pituitary or hypothalamic tumor would be a rare finding in these patients who were all screened with prolactin levels at the beginning of the diagnostic evaluation. However, if there is no cause apparent from the history, it is sometimes suggested to get a baseline CT or MRI scan of the sellar region to rule out a (very rare) tumor.
