Your symptoms point to pelvic organ prolapse­, a condition where pelvic muscle­s weaken. This causes ute­rus, bladder or bowel to bulge into vagina, causing discomfort. For re­lief, try pelvic floor exe­rcises - these stre­ngthen muscles. You could also use a pe­ssary device to support organs. If case is se­vere, surgery may he­lp.

Symptoms you may be experiencing can be due to hormonal changes, which may not be indicative of pregnancy. An irregular period can cause the hormone levels to fluctuate, leading to tender breasts, bloating, and mood swings. Stress, diet, and lack of exercise can also be the reasons why your body is affected this way. Try managing stress, eating healthy, and gentle exercise to help balance your hormones.

If you are observing a shorter than usual menstrual period, it could be that the cause is stress, hormone imbalance or a certain drug. It is advisable to visit a physician who specializes in women's reproductive health in order to diagnose the problem and to receive proper treatment.
 

You should get it checked by a specialist as soon as possible. It could be a sign of breast infection, cysts or even breast cancer. Just be sure to visit a specialist and get a proper diagnosis.

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 could be due to a variety of reasons like stress, illness, or pregnancy. It's important to take a pregnancy test to rule out the possibility of pregnancy or else you should consult a gynecologist for a proper evaluation. They will be able to provide a diagnosis and recommend appropriate treatment.
