My wife and I have intercourse atleast five to six times a week.But, my wife gets into periods even though I regularly ejaculate inside her vagina . We consulted a gynecologist and she suggested to have intercourse every alternative day from 10th day of last period start date, i.e. start date of last period was 1st of october and we participated in sex on 10th, 12th, 14th, 16th, 18th, 26th (yesterday) and all these time I ejaculated inside my wifes vagina but my wife is in periods again today (27th). Can you please advise?
