To be honest, I am a little embarrassed asking this one but can?t find an answer anywhere! Trying to get my head around ovulation and fertility time tables is turning into my personal soap opera. We conceived our first child first time lucky and had thought number 2 would be as easy....now here I am worrying myself silly reading every article going on best ways to increase your chances etc as it is proving much harder this time. The problem is that they are sooo contradictory - particularly on issues to do with sperm lifespan and when/when not to have sex. I thought this would be an easy one but if you believe Miriam Stoppard, sperm is only able to last about 24 hours and an egg 12 hours....if this is the case why do others say have sex only 2-3 days and that sperm can last for days, if you want a girl have sex no closer than 3 days before ovulation????? Aaaaagh my head is full of facts and contradictions, I have no idea what I am doing!!!!! I have a long and irregular cycle so it is difficult to predict ovulation anyway - anywhere between day 14-24!! So if anyone out there can put me straight once and for all / recommend a really good site of reliable information, I would appreciate it.
