hi do you know how your cycle works? and you know about male sperm? ok male sperm if your having lots of sex then he could be ejaculating immature sperm immature sperm wont make you pregnant he needs to take a two week break and let his sperm mature that could be one reason. so for you your cycle works like this lets see if this helps you so your cycle day 1 first day of your period day 14 give or take a day is ovulation day now you husbands sperm needs to be in place for this and it takes 3 days for it to get there after unprotected sex and once its there can live for around 7 days but its best if you have sex around day 9 the sperm splits up some goes the left ovary and some to the right so your egg drops from your ovary and away you go hopefully to pregnancy if on day 21 you get spotting its because its implantation day the day the egg implants itself into the womb lining. so after this if you miss your period wait a week then you do either an hpt or best see your doctor for a test. do hope this helps you. good luck
