i have try to make my wife pregnant, some days before her ovulation even in her ovulation, before her menstruation i have tried all this but to no avail. what will i do next?
If it has been more than about a year of trying, unsuccessfully, then you both need to see a fertility specialist.
You both can expect complete physical exams. She'll have an internal exam and labs drawn. You'll have a sperm count performed.
Hope it helps, good luck.
