Ttc baby

Me and my boyfriend have decided we are gunna start trying for a baby in the new year!! We started taking pregancare vitamins for him and her on 26/12/20 and I’ve started having a cup of resparbery tea a day. I’m starting to track my ovulation with clear blue ovulation sticks and tracking my temperature. Is there anything else we need to add? Also I seen some people have sex two times daily when it’s peak or high would you recommend doing it twice daily or not? Also do you just have sex the 4 high days or for the full 7 days
