The effects of ovulation medications?


Hello, I became pregnant in March of this year, but the embryo was lost naturally before reaching four weeks.
I started taking ovulation medication in May and June, but I have not conceived.
However, I noticed that since taking the ovulation medication, I experience breast tenderness about 10 days before my period.
Now in July, I am no longer taking the ovulation medication, but I still experience breast tenderness around 12 days before my period.
Is this normal? I have thyroid antibodies, but they are well-controlled.
Will this still affect my ability to conceive? Please provide me with an answer.
Thank you!

Hello! Before menstruation, experiencing breast or abdominal tenderness is a normal response caused by hormonal changes leading to increased blood flow in the breast or abdominal vessels.
If you feel very uncomfortable, taking some pain relievers can help.
Generally, infertility is defined as not achieving pregnancy after one year of trying, so you should keep trying, as there is a chance of conception.
Regarding your well-controlled hyperthyroidism, it should be beneficial for conception.
Wishing you success in achieving pregnancy soon.

More Info


The use of ovulation medications can significantly impact menstrual symptoms and fertility, and it's important to understand how these medications work and their potential side effects.
Ovulation medications, such as Clomiphene Citrate (Clomid) or Letrozole, are often prescribed to women who are experiencing difficulties with ovulation. These medications work by stimulating the ovaries to produce eggs, thereby increasing the chances of conception. However, they can also lead to various side effects, including changes in menstrual symptoms.

In your case, experiencing breast tenderness or pain (mastalgia) in the days leading up to your menstrual period can be a common side effect of hormonal fluctuations caused by ovulation medications. These medications can increase estrogen levels, which may lead to breast tissue swelling and discomfort. It's also worth noting that hormonal changes can persist even after discontinuing the medication, as your body may still be adjusting to the previous hormonal environment.

Regarding your concern about the impact of thyroid antibodies on fertility, it's essential to understand that thyroid function plays a crucial role in reproductive health. If you have thyroid antibodies but your thyroid function is well-controlled, it is less likely to affect your fertility. However, it's always advisable to have regular check-ups with your healthcare provider to monitor your thyroid levels, especially when trying to conceive.

Breast tenderness before menstruation can also be influenced by other factors, including stress, diet, and lifestyle changes. If you notice that the breast pain persists or worsens, or if you have other concerning symptoms, it would be prudent to consult your healthcare provider for further evaluation.

In summary, while breast tenderness can be a normal response to ovulation medications, it is essential to monitor your overall health and fertility. If you have concerns about your menstrual symptoms or fertility, especially in the context of your thyroid condition, discussing these with a healthcare professional who specializes in reproductive health can provide you with tailored advice and support.
