instead of a woman to try and conceive unsuccesfully for a long time, wont it be advisable for her to get a little knowledge first as that can change her results dramatically.
these are some of the best kept secrets of TTC [trying to conceive]
1. ovulation signs are not 100% reliable, and even the ones that are, are usually interrupted by womens overanxiety to conceive, if a woman wants to time her ovulation, it will be best to use maybe two to three signs for confirmation.
a sign of ovulation people are unaware of is ' increased cervix position'

2. having sex only during ovulation period has proven not to be good, when TTC, a lady should have sex frequently, this is because sperm quality diminishes in a man's body after some time

3. a woman should try to reach orgasm everytime during sex, when she does that, her vagina secretes alkalines that sustain the sperm for a long time.
