Heavy cramps synonymous to PMS on day 11 after IUI, no breast tenderness or any other pregnancy related symptoms. Bad sign?
No. Be patient . Its too soon to worry yet. Breast tenderness comes later and is not always present in every woman.
Take a test . You can not draw conclusions regarding pregnancy based on these symptoms. If you think you might be pregnant check then check a home pregnancy test. They are cheap, reliable and available at any pharmacy. The best time is if you miss your period.
