NO more birth control advice

Just finished my last pack of birth control & now in the menstrual phase just patiently awaiting my fertile window. My BFF just had her baby girl  & it has me so anxious and excited that maybe it will happen for us (she was on birth control when she got pregnant). Does anyone have any tips for someone just coming off the combination pill? And what is the best time of day to take prenatal vitamins, I have heard they make some women nauseous. Pointers for someone just ttc would be great as well. We always try, but I don't know any little tips or tricks to try out! I'm open to anything :)
