I have several questions and I will admit that I am a little ignorant to this subject. I have never been on any birth control with the exception of the "pull out method". My husband and I have now been actively trying to get pregnant for 5 months and no luck so far. I did miss my period by five days one month but then I started; was I pregnant? I have been charting my cervical fluid and using an ovulation calculator from BabyCenter.com once I figure out the timeframe that I could be pregnant we have sex two days before and two days after and every other day in between. If an egg does get fertilized could having sex and the "extra" ejaculate harm the fertilized egg and prevent it from attaching to the the wall? Also I run a lot and I have often worried that running will stress my body; will that prevent the egg from staying attached?
Thanks for the help!
