My boyfriend is visiting me this weekend ..

Felicia • It Works Global Distributor
According to Glow .. This is my most fertile time (starting today). I take OPK twice a day. 
Should my boyfriend and I have sex Friday, Saturday and Sunday? Or should it be every other day as in Friday and Sunday? 
If I get a positive OPK tomorrow or Saturday or Sunday, I don't want to miss a chance ..
What do you all think? :) any advice or suggestions would be greatly appreciated.
