Why is conceiving the second time harder we got pregnant on our fifteen month old son first attempt and now its fourth still not pregnant. used an ovulation kit detected LH surge.?

There are many possible reasons why conceiving a second time may be harder than conceiving the first time. Some of these reasons include:

- Age: As women age, their fertility naturally declines, making it more difficult to get pregnant. This is because the number and quality of eggs a woman produces decreases with age.

- Weight: Being overweight or obese can affect ovulation and make it more difficult to get pregnant. This is because excess weight can disrupt the balance of hormones in the body, interfering with ovulation.

- Stress: Chronic stress can affect ovulation and make it more difficult to get pregnant. This is because stress can raise levels of the hormone cortisol, which can interfere with the menstrual cycle.

- Lifestyle factors: Smoking, drinking alcohol, and using recreational drugs can all affect fertility and make it more difficult to get pregnant.

- Underlying medical conditions: Some medical conditions, such as thyroid problems, diabetes, or polycystic ovary syndrome (PCOS), can affect ovulation and make it more difficult to get pregnant.

In addition to these factors, it is also important to consider the timing of intercourse when trying to conceive. The most fertile time for women is the window of time around ovulation, which typically occurs 14 days before the start of the next period. For women who have regular menstrual cycles, this means that the most fertile time is typically 10 to 14 days after the start of their period.

If you have been trying to conceive for a year without success, it is important to talk to your doctor. They can help determine the cause of infertility and recommend the best course of treatment.

Here are some tips for conceiving a second time:
