Hello, Never take medicines without clinical examination and consultation by a doctor. Krimson 35 is not an emergency contraceptive pill. It is commonly used to treat PCOS. It helps to regulate periods and also hormones. Don t worry about side effects. They will go away as the body adjusts with the hormonal changes. Presently you are having spots, one-two dark spots. Wait for a few days, the periods should come. If you miss the periods, you should get a pregnancy test done with the first morning mid-stream urine. Get clinically examined by a gynae, get per vaginal check-up done for bulky uterus. You should also get USG done to confirm pregnancy, ectopic pregnancy, etc. In case you are not pregnant then you will have to get few more blood and imaging tests done to detect PCOS, anemia, perimenopause, stress, fibroids, endometriosis, etc. You will be accordingly treated. Stay away from addictions like smoking, alcohol, drugs, etc. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
