Why Am I Bleeding and Experiencing Pain for 3 Weeks with Smelly Blood and Lower Stomach Pressure?

There is no chance of getting pregnant from sperm touching your skin.

It's common for menstrual cycles to vary occasionally in length, and a delay of a few days is not a serious issue always. Norethisterone is usually prescribed to delay periods, but if you've taken the medicine and still haven't got periods then consult your doctor. 

It is advised to visit a gynecologist for a thorough check-up and evaluation. Also doctor can prescribe contraceptives to avoid unwanted pregnancy

Periods can be missed due to pregnancy, or other medical conditions. Factors like stress and weight fluctuations can disrupt hormonal balance while certain medications or medical conditions can also affect menstrual regularity. 

Urine infections and bladder troubles often cause pelvic pain and frequent urination. Common germs invade urinary tract parts, like the bladder or kidne­ys, sparking UTI. But irritants -- foods, drinks -- may also disturb the bladder, leading to the same issue­s. Hydrating well and dodging irritants helps relie­ve symptoms. However, see doctor for prope­r assessment and cure.

Emergency contraceptive pills, like the one you took.. can cause changes in the menstrual cycle including lighter or irregular bleeding. The bleeding you are experiencing could be due to the pill or your regular period. It's important to take a pregnancy test if you have concerns about pregnancy.

You don't need to stress about nipple discharge during pre­gnancy - it's a natural thing called colostrum, this whitish fluid is your body's way to nourish the baby soon. If its bothering too much, use mild soap and water to clean the area ge­ntly. But watch for redness, swelling or discomfort - as it warrants medical attention.
