hello and thank you for asking HCM,
I understand your concern. It is not to early to make a pregnancy
test at the time you are expecting your next period. My suggestion is to make the test because these symptoms could be premenstrual but also connected with early pregnancy. If the test is positive visit your gynecologist to start with prenatal care
. If it is negative and you don't get your period, also visit your gynecologist to make a proper examination because of the symptoms you are having.
I hope this answer was helpful to you.
