and it does not stop periods. Your doctor may have switched over from the combination pill to a progestogen-only pill to avoid the side-effects of estrogen
that have manifested. Micronor does not usually inhibit ovulation and pregnancy
can occur. The cause of the delay in periods could be impaired hypothalamo-pituitary-ovarian function as well as pregnancy. You can go for a serum beta-hCG test and get a trans-vaginal sonogram a few days later to know the cause and exclude/confirm pregnancy. Also, excess weight leads to orthopedic problems as well as hormonal
disturbances and you should try to maintain a healthy BMI. Hope this information is useful. Take care.
