I am trying to get pregnant my periods was june the 5 when will it be the best time?

It depends: It depends on the usual length of your cycle.Ovulation usually occurs 14 days before ur next period starts.If ur periods r regular u can count backward, u can also check ur cervical mucous which becomes egg-white like at ovulation, or chart ur temperature before u get out of bed each morning looking for an about 1/2 degree rise that happens with ovulation, or just use an ovulation predictor kit.
