remember a man produces 85 million sperms every day, and it only needs one sperm to find its way to the egg you release from your ovary for you to get pregnant.
so its good to have intercourse often to increase your chances. but if you are having intercourse 3 times a day every day, he is soon going to run out of mature sperms. they take a while to grow and mature.
its good if you love sex and want to do it often with each other for the pleasure it brings, but if you are trying to get pregnant, it may be better to only have sex once a day, every other day.
That will give him a chance to produce some sperm that mature properly before he ejaculates them.
Also if you know when you ovulte, that is the best time to have sexual intercourse , because a sperm is more likely to meet your egg at that time.
Sometimes you can tell when you ovulate , because your vaginal discharge changes.
The amount of normal discharge varies from woman to woman, and with the menstrual cycle. Many women notice that during the week after a period there is hardly any discharge, and what there is has a thick consistency. Towards the middle of the cycle (about 2 weeks after the start of a period) the amount increases and it becomes thin, slippery and clear, like uncooked egg white. When this discharge is exposed to the air it becomes brownish-yellow, so it is normal to find a yellowish stain on your undies at the middle of the monthly cycle. There may also be a feeling of moistness and stickiness.
Discharge also increases during pregnancy. And during sexual excitement, vaginal discharge becomes very profuse because two glands near the vaginal opening (the Bartholin's glands) secrete additional slippery mucus, which acts as a lubricant for intercourse.
