1. Your age is over 35: Biological clock is an important risk factor. As women age, fewer eggs become available for ovulation and egg quality deteriorates. As a result, after age 35, fertility potential starts to decline and eggs become more susceptible to chromosomal abnormalities. Women over 35 also have a higher chance of miscarriage.
2. You have irregular periods and/or experience bleeding or spotting between periods: This might be an indication of ovulation problems which is a cause of infertility.
3. You have a history of recurrent miscarriages: These may be caused by abnormalities of the uterus. An infection of the uterus or low hormone levels can also trigger recurrent miscarriages.
4. You are extremely underweight or overweight: Being overweight can result in overproduction of estrogen and this may prevent pregnancy. Being underweight can result in a lack of estrogen, which might disrupt the menstrual cycle.
5. You and/or your partner have chronic diseases such as diabetes or hypothyroidism: These diseases can hinder embryo implantation.
6. You have history of sexually transmitted diseases (STDs) such as chlamydia and gonnorhea: These can result in pelvic inflammatory disease and blocked fallopian tubes.
7. You have abnormal pelvic pain during your periods or sexual intercourse: These symptoms may indicate endometriosis, tubal disease, pelvic inflammatory disease, or fibroids, all of which can negatively affect fertility.
8. You smoke or consume excessive amounts of alcohol: Both are detrimental on reproductive health of males and females.
