Don't overdo it--more sex doesn't mean higher chances
The more you have sex, the more likely you will be to get pregnant - right? Well, while this might seem like a natural progression, more sex does not necessarily mean you will get pregnant. It is all about trying at the right time. After all, you could have sex 1,000 times when you are not ovulating and not get pregnant, whereas you could have sex once when you are and conceive.
Plus, sex is usually enjoyable, and you never want it to become a stressful activity. If you find yourself having sex three times a day in order to conceive and are not seeing any results, you will begin to get frustrated at the whole thing. Plus, the more a man ejaculates, the less semen will be produced each time. So, make sure that you know when you are ovulating and have sex accordingly, and of course - whenever you want to!
