Hello, Yes, you should not. Crisanta LS is itself contraceptive pill so you should not take this medicine if you are trying to conceive. Whether you are trying to clear up your skin, regularize your period s or ease disruptive and painful PMS, keep in mind that hormonal birth control pills which you are taking are only masking the symptoms and are not solving the problem. Your body is actually trying to tell you something! And these pills are not free of side effects. The synthetic estrogen in birth control pills can cause short term side effects like GI upset, mood swings, irregular bleeding or spotting. And even scarier than the “mild” side effects are the serious health risks that accompany birth control pills. These include: Increased risk of cervical and breast cancers Increased risk of heart attack and stroke Migraines Higher blood pressure Gallbladder disease Infertility Benign liver tumors Decreased bone density Yeast overgrowth and infection Increased risk of blood clotting Cancer, heart disease, stroke, infertility. Surely these side effects make birth control pills a less than desirable option for contraception, and even less desirable for masking acne, period problems and PCOD. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr AJEET SINGH, General & Family Physician
