Hi Anonymous,
Welcome to Empowher and thank you for your question. Let me begin by explaining that a test for pregnancy, whether it is a blood test or urine test, detects levels of hCG. hCG stands for human chorionic gonadotropn which is a pregnancy hormone. It is only produced by the placenta. The placenta is the temporary organ that joins the mother to the fetus. hCG levels can first be detected as early as 10 days after conception. Generally, hCG levels will double every 72 hours and peak in the first 8 to 11 weeks of pregnancy then decline and level off for the remainder of the pregnancy.
The thyroid gland produces thyroid hormones thyroxine or T4 and triiodothyronine or T3. Thyroid problems are either hypothyroidism, in which the thyroid gland does not produce enough thyroid hormones or hyperthyroidism, in which the thyroid gland produces excessive amounts of thyroid hormones. Interestingly, hCG and estrogen can cause increased thyroid hormone levels in the blood during pregnancy.
Functional ovarian cysts develop in the normal process of ovulation.This type of cyst can be stimulated by hCG and another hormone called FSH..
So, putting all this information together, an ovarian cyst or thyroid problem will not have an impact on a home pregnancy test.
It is possible to get a false-negative result if you took the test too early, time the test wrong, or used diluted urine. For the most accurate results, always test the first urine of the morning, wait one week after a missed period before testing and follow the directions carefully.
You could try another home pregnancy test or make an appointment with your doctor or visit a health clinic to have a blood pregnancy test, which is very accurate.
