Taking novelon 21 days course for irregularities in period, missed period in sept, completed Meprate course, prolactin was 50.1 so completed cabergoline 0.5 mg 4 week course, got periods within 4 days from last dose. Usg pelvis - 28mm dominant follicle in one ovary. Now started Novelon since day 2. Can I have unprotected sex during this time? It's a contraceptive so do I need to use protection or will I get pregnant?
