Hi and thanks for the query,
From what you describe, it is more probable that this should be ovulation bleeding or what is called the Mitlmerzc. If you do not have irregular periods
in the past and you think your period is overdue, it is safe and reasonable to do a pregnancy
test. However, taking the test too early might proof negative, and maybe retaking the test 2 weeks later might be more appropriate.
Thanks and best regards,
