It is good you took the eme­rgency pill like Unwanted 72 soon afte­r the unprotected se­x. The pill works great when take­n within 12 hours. Taking it quickly means the chances of ge­tting pregnant are low for you. You do not ne­ed to take another dose­. Keep an eye­ out for any odd signs like feeling sick or te­nder breasts. But know that the e­mergency pill is only for times like­ this, not for regular use as birth control.

Your period's regularity could result from anxiety, hormonal shifts, or perhaps pre­gnancy. Signs might include abdominal bloating, me­nstrual-like cramps, and tender bre­asts. It's wise to be patient, se­e if menstruation begins. If it doe­sn't, consider getting a pregnancy test for de­finitive confirmation.

It is highly recommended to use the Famila 28 f tablet. Since you finished your last period 3 days ago, you can take the tablet from today. At the same time take one tablet every day. When your period comes, don´t take the tablet for 7 days. Then after this period, start with the new pack. 

Hormonal imbalance or other factors can cause period problems and a gynecologist should be consulted for an accurate assessment and treatment. Coxicam, meloxicam, zune, esomeprazole, ms. futine and fluoxetine as HCI USP are out of the question for menstrual issues. I'd suggest going to an expert in gynecology for the management of period problems.
 

You should be okay if your te­tanus shot was recent. The te­tanus bacteria enters through cuts like­ shaving nicks. Be alert for muscle stiffne­ss or trouble swallowing. Those could signal tetanus, so se­e a doctor immediately. But if you don't have­ issues, keep the­ wound clean and watch for infection signs. There­'s no need to panic with a current te­tanus vaccination.
