You are going through a tough time with stress and sleeping troubles. Stress can interfere with sleep, and in some cases, it can even worsen illnesses such as asthma and anxiety. The most common cause of insomnia is stress. You can try relaxation techniques like deep breathing, gentle exercise, and avoiding caffeine or screens before bed. 

The 17th starting and the 20th ending period is a pretty normal cycle. Having unprotected sex on the 22nd might expose you to the risk of getting pregnant. So, watch for possible symptoms like nausea, fatigue, and breast tenderness. If you're concerned, think about using emergency contraception or taking a pregnancy test. 

There are many potential causes for this, but one is especially common: stress. When stressed out, it can throw your whole cycle off, leading to a late period. Missed periods can also be due to fluctuating hormones. If you’re concerned about being pregnant take an at-home test. 

Even if you use a condom, there's still a small chance of pregnancy if there was contact between the genitals. But, if the ejaculation was avoided, the chance is very low. So, nothing to worry about if you're late at times in your periods. A physical examination and pregnancy test after a week or so will be useful for a positive result to confirm that you are pregnant or not. 

A delayed period can be due to many reasons. It's common . Pregnancy, stress, and weight changes can affect your menstrual cycle..Other causes may include thyroid issues, eating disorders, or polycystic ovary syndrome. If you miss more than one period, consult a DOCTOR.
