Why is the 12 week pregnancy rule so important?

The first trimester of pregnancy can be a challenging, stressful time for new mums, especially if they’ve had fertility issues.

What makes it even harder is the unwritten “12 week rule”, that women feel they should adhere to, which says they should not share their news with others or announce it on social media until they are 12 weeks into their pregnancy. So, why does the “12 week rule” exist?

From a medical point of view, the 12 week mark is considered a “safe” point during the pregnancy, although women can still suffer miscarriages at any point during gestation, though it becomes much less common as time goes on.

Research has previously shown that at 8 weeks, the chances of having a live pregnancy is 92%, increasing to 97% at 12 weeks gestation. However, obstetricians have reported that there are no actual clinical guidelines as to when a woman should or should not announce her pregnancy.

Fertility First always performs the first pregnancy scan for a patient at 6 to 7 weeks gestation and if the fetal heart is well established, there is less than a 5% chance that pregnancy will result in a miscarriage. It is crucial for women to feel supported during the announcement of their pregnancies and in the even of an early pregnancy loss, that support is even more important.

FAQs about improving natural fertility

Will stress affect my ability to get pregnant?

Yes, chronic stress can impact fertility by disrupting hormonal balance and ovulation patterns. Managing stress through relaxation techniques, regular exercise, adequate sleep, and mindfulness practices may help optimise your chances of conception. Consider speaking with a counsellor if stress feels overwhelming.

How does my partner's health affect our fertility?

Sperm health accounts for about 40% of conception challenges. Your partner can improve sperm health by maintaining a healthy weight, avoiding excessive heat exposure (hot tubs, saunas, tight clothing), limiting alcohol, quitting smoking, managing stress, and taking a multivitamin with antioxidants. Sperm takes about 3 months to develop, so lifestyle changes need time to show results.

When during my cycle am I most fertile?

Your fertile window typically spans 5-6 days, ending on ovulation day. For a regular 28-day cycle, this usually falls between days 10-15, with peak fertility 1-2 days before ovulation. Track your cycle using ovulation predictor kits, basal body temperature, or cervical mucus changes to identify your unique pattern. Having intercourse every 1-2 days during this window optimises your chances.
