You can get pregnant but not stay pregnant (recurrent miscarriage) because of genetic issues, like chromosomal abnormalities in the embryo, hormonal imbalances (e.g., thyroid, progesterone), uterine problems (fibroids, polyps, septum), autoimmune conditions (like antiphospholipid syndrome), or clotting disorders, which prevent healthy implantation or development, leading to early pregnancy loss. While most early miscarriages are random, recurring losses often point to underlying, treatable medical factors.
Some women may be born with an irregularly shaped uterus, and some women may develop abnormalities with their uterus over time. A woman's immune system may also play a role in recurrent pregnancy loss. Hormone abnormalities may also impact pregnancy loss, including thyroid disease and diabetes.
Below are the main signs that could suggest secondary infertility.
Chronic or acute infections can lead to inflammation and immune activation, causing the uterus to reject the embryo. Congenital anomalies in the uterus can make it less supportive of implantation. Hormonal imbalances can indirectly impact the immune tolerance mechanisms.
Risk Factors
Health issues, such as chronic diseases, in the mother that can also increase risk for pregnancy loss include: Chronic diseases, such as high blood pressure, diabetes, thyroid disease, or polycystic ovary syndrome (PCOS) Problems with the immune system, such as an autoimmune disorder.
You know you might be infertile (or facing fertility issues) primarily by the inability to get pregnant after a year (or six months if over 35) of regular, unprotected sex, but symptoms in women can include irregular/painful periods or no periods, while men might have issues with sexual function, hair growth, or testicular pain, all signaling a need for medical evaluation with tests like blood work or ultrasounds.
Some factors that can cause a weak pregnancy include hormonal problems, chronic diseases, genetic issues, infections, immune disorders, or other medical complications.
If any of the following signs occur, the woman should be taken immediately to the hospital or health centre.
Five signs of a weak immune system include frequent infections, slow-healing wounds, persistent fatigue, ongoing digestive issues, and getting sick with things that last a long time, like a cold that lingers or severe infections requiring strong treatment. These indicate your body struggles to fight off pathogens or repair itself effectively.
A pregnant woman's immune system identifies the embryo as an attacker and produces antibodies against it. That results in the failure of embryo implantation or recurrent pregnancy loss. These women have high levels of Natural killer cells that destroy substances they detect as invaders.
Infertility in women
A study in the medical journal Reproductive Toxicology found that those who took supplemental folate and vitamins B6 and B12 lowered their homocysteine levels, which improved the odds of successful conception in women with recurrent pregnancy loss.
For men, some of these signs include a healthy sperm count, high-quality sperm that can swim quickly and easily, and a good balance of hormones. For women, good fertility indicators include regular ovulation, the presence of cervical mucus, and the regularity of menstrual cycles.
A woman's peak reproductive years are between the late teens and late 20s. By age 30, fertility (the ability to get pregnant) starts to decline. This decline happens faster once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely.
The following tests are recommended:
You can increase your chances of getting pregnant again if you are in good health. It is also important that your partner is healthy. A bad diet, smoking, drinking and unhealthy working conditions can affect the quality of sperm and prevent pregnancy happening.
Eating a healthy diet, exercising regularly and getting enough sleep can all strengthen your immune system. Reducing your stress levels can also boost your resistance to disease and infections. Staying up to date on vaccinations gives you the most protection against those pathogens.
Common Autoimmune Disease Symptoms
An immunoglobulins blood test can help your health care provider diagnose different types of health conditions that may affect your immune system. A variety of conditions can cause abnormal levels of IgM, IgG, and/or IgA, such as: Autoimmune disorders.
The "3-2-1 Rule" in pregnancy is a guideline for first-time mothers to know when to call their midwife or doctor for active labor: consistent contractions that are 3 minutes apart, lasting 2 minutes each, for 1 hour (or sometimes cited as 3-1-1, meaning 3 minutes apart, 1 minute long, for 1 hour). For subsequent pregnancies, the 5-1-1 Rule (5 minutes apart, 1 minute long, for 1 hour) is often used, indicating labor is progressing more quickly.
Red flags to look out for in pregnant women include severe back pain, bleeding, headaches, and high fever.
Main symptoms
Hydration plays a key role in keeping your energy up. Aim to drink at least 64 ounces (about 8 cups) of water daily. Here are some tips to make staying hydrated easier: Use a refillable water bottle to track your intake.
Pregnancy presents the immune system with a unique challenge. For the mother, the embryo contains antigens from both her own body (self) and from the father (non-self). Due to the presence of paternal antigens, rejection of the embryo by the mother would be expected.
