Is Menstruating Twice Monthly Normal?

There are many reasons why periods get missed like stress, lifestyle changes etc. If you think it is because of pregnancy, I suggest you to visit a gynecologist and get some pregnancy tests done to confirm it. 

In case couples choose to have no further children, then, "tubal ligation" which is commonly known as tube tying, is the most suitable approach to use. This process is successful and risk-free. However, when tubal ligation cannot occur maybe probably or fails, then, your partner can opt for vasectomy. Vasectomy is a brief surgical procedure that blocks the sperm from reaching into the semen hence no chances of causing pregnancy to a woman. After either of these two techniques has been done, none of them can be turned back to its normal state, so make up your mind about them wisely.

Pre­gnancy risk is present if sperm e­nters the vagina. Although chances are­ reduced without intercourse­, it remains possible. Signs indicating pregnancy include­ missed periods, nausea, tire­dness, and sore breasts. A pre­gnancy test provides confirmation. Moving forward, condoms offer crucial prote­ction against unintended pregnancie­s and sexually transmitted infections.

On average, the menstrual cycle lasts from 3 to 7 days. There are pregnancy possibilities even if having sex at any time, but the chances are greater during ovulation, which usually occurs on the 14th day of a normal cycle. If your period started 4 days ago and you have a 28-day cycle, ovulation could be in place now. 

4 months of missed periods at 21 years old is abnormal. All these appear to be connected with weight loss, hair fall and stress. Set up an appointment with a doctor to review possible causes and possible treatment.

After taking the emergency contraceptive pill, it is common to experience changes in your menstrual cycle. The bleeding could be a withdrawal bleeding or a side effect of the pill. Howeevr, it's best to consult with your doctor for a evaluation and personalized advice. 

Sometimes the cause of the hymen breaking can be due to different factors such as exercise, tampon use, or simply natural growth. Once shattered, a hymen can never grow back.

The AMH and FSH levels you provided probably offer some information about fertility potential, but they cannot definitively determine if pregnancy is possible. Low AMH levels may suggest reduced ovarian reserve, while high FSH levels indicate diminished ovarian function. Other factors can also influence fertility.. and it's best to consult with a fertility specialist for a proper evaluation and personalized advice based on your situation.

It seems that you may have a yeast infection. The yeast is a very small germ that can cause itching of the skin and can lead to a white, cheese-looking discharge. You may use OTC antifungal creams to assist in getting rid of the yeast. Make sure to wear comfortable, breathable clothing and avoid using scented products in that area to help avoid infections in the future.
