You have polycystic ovary syndrome and irregular menstrual cycles.
Your period started on March 6 and lasted until March 16 with only a small amount of bleeding.
You had intercourse on March 16 using a condom, and the next day you experienced a little bit of bleeding and some blood clots.
In this case, if you used a condom during intercourse, it is unlikely that you will become pregnant.

When it comes to the question of whether you can get pregnant with irregular periods while using protection, it's important to understand a few key factors regarding ovulation, menstrual cycles, and the effectiveness of contraceptive methods.

Firstly, having irregular periods, often associated with conditions like Polycystic Ovary Syndrome (PCOS), can complicate the prediction of ovulation. In a typical menstrual cycle, ovulation occurs approximately 14 days before the start of the next period. However, with irregular cycles, this timing can vary significantly, making it difficult to determine when you are most fertile.
In your case, you mentioned that your last menstrual period started on March 6 and lasted until March 16, with only a small amount of bleeding. Engaging in sexual intercourse on March 16 while using a condom is a protective measure against pregnancy. Condoms, when used correctly, are about 98% effective at preventing pregnancy. However, no contraceptive method is 100% effective, and there is always a small risk of failure due to factors such as breakage or improper use.

The bleeding you experienced after intercourse could be due to several reasons, including hormonal fluctuations, the presence of a small amount of endometrial tissue, or even irritation from sexual activity. If you are concerned about the possibility of pregnancy, it is essential to consider the timing of your cycle and the effectiveness of the protection used.

Given your history of irregular cycles and PCOS, it is advisable to monitor your menstrual cycle closely. If you miss your next period or experience unusual symptoms, such as nausea or breast tenderness, consider taking a home pregnancy test or consulting with a healthcare provider for further evaluation.

In summary, while the use of condoms significantly reduces the risk of pregnancy, the irregularity of your menstrual cycle and the timing of ovulation can complicate matters. If you have concerns about your menstrual health or potential pregnancy, it is always best to consult with a healthcare professional who can provide personalized advice and guidance based on your specific situation. Additionally, if you are looking for more reliable contraception, discussing options with your healthcare provider may be beneficial, especially considering your history of PCOS.
