For me OPK CD18,19,20. I BD CD18,19,20. Lol. Cos after that husband has to leave the country. I was damn impatient, I couldn't wait for the alternate day rest for him. Decided he should just do his job all 3 days!
Prior to that on CD17, went to gynae, he say 1 egg about to be released but he felt would be released after CD22 based on size. Well hubby already not around liao, so who cares about what the gynae say anymore, so jus BD.
Also took multivits, royal jelly (they say give nice healthy big eggs), folic acid and longan red date tea (1 cup) daily. After BD put 2 pillow under hips for at least 20mins but for 2 nights I fell aslp with the pillow, maybe gravity helped too.
Jiayou to all TTC!
