Switched to it 3 weeks ago to help manage PMS, GP warned about side effects but suggested 3 months to adjust. 2 weeks was business as usual, then 3 days of spotting with kind of energy and mood crash like the worst day of PMS. This evened itself out but the boobs seem to have gone bigger and really sore, bras, clothes, everything hurts. Is this going to be on off all the while, or first three month on off, or non-stop 3 months? Can even lean forward without feeling it.
