Hello and thank you for using HCM! I was intrigued by your question and I want to give an answer. The easiest and quickest way to determine a pregnancy are home pregnancy tests! As you know the procedure is fast, simple, cheap and non-invasive. Although sometimes home pregnancy tests are incorrect (for example, the test tells you are pregnant when you are not in reality - false positive, or vice-versa: the test tells you are not pregnant when in fact you are - false negative, and this incorrectness rate might vary between 80-95% of times depending on the type of test), they are the most used pregnancy test worldwide. Coming back to your situation: if you wish to frequently assess whether you are pregnant or not, then I assume that you will continue to use home pregnancy tests, for the reasons I listed earlier. However, if you doubt that any other reason might interfere with your fertility ability, then you should consult a doctor and try other examinations to determine your pregnancy status. I hope my answer will help you! Thank you!
