Hi I hope that I can help you. If your periods are regular, then you ovulate about 14 days before you are to start your next period. If they are irregular, then it is most likely 12-15 days before you start, depending on the length of your cycle. It helps to chart your periods for at least two months to have a feel for when you will ovulate. And when you know, start having sex about a week before. That way if you are off or you cycle is weird, you have a better chance of hitting a golden day. Another thing to make sure is to have sex every other day. Sperm live in your body for up to 72 hours, so going one day without wont hurt your chances, it may actually increase them. Postion doesn't make much of a difference, but try to prop your pelvis up for at least 30 mins after to help the sperm travel. And try not to use any lubricate. It can hinder the process, and if you must, use olive oil. Also dont douch, it changes the ph levels in the vaginal enviroment and can make it difficult to concieve. And most importantly, dont stress. That has been shown to decrease your likelihood of conception. Just let go and hopefully in a few months you will find yourself pregnant! Let me know how it goes.
