2nd Day High Fertility... tips for TTC

Okay, despite the obvious 'deed' that needs to be done in order to get pregnant. Anyone have Any tips, tricks on how to make the most of A positive (high fertility) test... ex: diet, supplements, activity etc?
We are 90 days out after an ectopic & were given the okay by our doc to try this month. So, pretty excited to see flashing smiley face the last two days (days 13 & 14). 
We couldn't want this more and would so appreciate any ( I mean any) info that could increase our chances of a seeing BFP in a few weeks;) 
Thanks in advance.
