Understanding pregnancy success rates and knowing when to test or consult your doctor is crucial for anyone trying to conceive, especially after previous pregnancies or complications. Based on your situation, here are some insights and recommendations.

Firstly, it’s important to understand that after giving birth, especially while breastfeeding, your menstrual cycle can be irregular. This is due to hormonal changes in your body as it adjusts back to a non-pregnant state. Breastfeeding can suppress ovulation, which may lead to delayed or absent periods. Your cycle may take some time to normalize, and this can affect your ability to conceive.

Given that you had your last menstrual period on December 9 and have been tracking your cycles, it’s advisable to wait until you have missed a period before taking a home pregnancy test. Most home pregnancy tests are designed to detect the hormone hCG (human chorionic gonadotropin) in your urine, which is typically present about a week after a missed period. If your cycles are irregular, it might be challenging to determine the best time to test. Therefore, if you suspect you might be pregnant, you could consider testing about two weeks after your last known ovulation or around the time you expect your next period.

If you continue to have irregular cycles or if you have concerns about your fertility, it would be wise to consult your healthcare provider. They can perform blood tests to check your hormone levels and assess your overall reproductive health. Additionally, if you experience any unusual symptoms, such as severe pain or heavy bleeding, you should seek medical attention promptly.

In terms of timing for a doctor's visit, if you have not conceived after several months of trying, or if you have irregular cycles that persist, it would be beneficial to schedule an appointment. The general recommendation is to consult a doctor if you have been trying to conceive for over a year without success, or for six months if you are over 35 years old.

Moreover, if you have had any previous complications during pregnancy or childbirth, such as miscarriages or issues with your menstrual cycle, discussing these with your doctor can provide valuable insights into your current situation. They may recommend further evaluations, such as ultrasound examinations or hormonal assessments, to better understand your reproductive health.

In summary, monitor your menstrual cycle closely, wait until you have missed a period to take a home pregnancy test, and do not hesitate to consult your doctor if you have concerns about your fertility or if your menstrual cycles remain irregular. Your healthcare provider can offer personalized advice based on your medical history and current health status, helping you navigate your journey toward conception more effectively.
