What should we do if my fiance missed her period after unprotected intercourse 12 days ago?

Late periods and vaginal dryness can have many causes of which stress, hormonal imbalances, and infections are included. Kindly seek medical help if you experience any uneasiness or unusual symptoms.
 

Late pe­riods can feel worrying; they could me­an pregnancy. You might feel nause­ous, exhausted, or nee­d the bathroom frequently. Howe­ver, stress, routine change­s also delay periods. Take a pre­gnancy test if you've missed; waiting a fe­w days gives accurate results. 

Frequent periods can be due to various factors like hormonal changes, stress, or certain health conditions. Treatments depend on the cause and may include hormonal birth control or hormone-regulating medication. Please consult a gynecologist for personalized advice.

Emergency contraception is intended for occasional and emergency use, not as a regular form of birth control. While there is no strict limit on how many times emergency contraception can be used, it's important to understand that it is not as effective or reliable as regular contraception methods.

Repeated use of emergency pills can disrupt hormonal balance in your body and cause irregularities in your menstrual cycle. It's recommended to speak personally with a gynec about more reliable and appropriate forms of contraception that can better suit your needs and provide ongoing protection.

The pain can be because of harmonal change, muscle strain or injury. Get it checked early to avoid any further problems.

The  treatment depends on the cause of the urine leakage. I advise you to visit a urologist in person first. Based on some evaluations, the cause of the problem can be known and accordingly the doctor may decide whether your mother needs surgery or medications. 

Irregular periods can have various causes, and taking medication to regulate them is a positive step. However, even with regular periods, occasional variations in timing can still occur. It mostly happens in maximum no. of women. if you feel you're experiencing pregnancy symptoms it may be a good idea to take a pregnancy test to rule out the possibility of pregnancy.
