Is a pregnancy test performed 12 days after intercourse reliable?

My previous menstrual period lasted seven days, it was less heavy as always until the next menstrual period was a delay of three days. I did a pregnancy tedt on the day I got my period to be sure negative and now it lasted three days, is that normal?

To @123:

Cyclodynone contains chasteberry extract, which helps reduce the symptoms of premenstrual syndrome (PMS) and regulate the menstrual cycle. For optimal treatment effect, it is recommended to take one tablet a day for at least 3 months. You should consult your doctor before using this medicine if you are taking products from the group of dopamine agonists, dopamine antagonists, estrogens or antiestrogens.

Cyclodynone 20 mg I read that it can be used in menstrual disorders, can you tell us something more if there are no indications.

To @123:

Yes, pregnancy can be ruled out.
