First of all thank you for the advices.@mirandalily i havent tried it yet...
you should also be checking your cervical mucus, for eg if your cervical mucus is eggwhite, jelly, stretchy the more fertile you are and that is the best time to have sex because that mucus help assist the sperm on there travels to the egg. also have you tried the saliva ferning microscope?
you should know when u r ovulating.2 days before and one day after are best for sex....get a medical checkup too for you and your partener to make sure that you two are medically fit. if you cycle is apprximately 28 days then you would be most fertile around 13th and 14th day of your cycle.
