Yeah that i would guess those days you have a higher chance for a girl? but to answer your other quest i had my jonas done by a girl on ingender who isnt there anymore,cant get a hold of her/Anyways it didnt work for me i just try to dtd on a gIRl day you can check through lunarium.uk and luckily i have oed in the new moon phase on a girl sign but havent conceived yet to test it out? You can try to do your own jonas date here although it is alot of calculations and difficult for some,it also doesnt always show girl or boy days like mine only shows 2-3 months of girl days and after its undecided,but anyways you go to extended chart select then choose special charts then from the drop down lunar phases fertility calendar .then add your info.
And i chose to drop the licorice root and long abstain and i added repfresh last time not sure yet if it worked but i felt more 'SAFE' using it,we did abstain first time to long and didnt get pregnant and 2nd time planned to do 6 or 7 days abstain but i oed early and did 4 days once on o day and the day after,i just want to conceive now,,im not bothered though as everyone says diet is the most important and timing least!Oh and the person who did my jonas date if you plant to use yours said you always dtd 24 hrs before the date and again 12 hrs after that..
