Is a missed/late period almost ALWAYS due to a missed or late ovulation? Or can you ovulate at your 'regular' time (whenever that might be) and still have a late period? This is assuming you're not pregnant.
Also...you can usually only get pregnant around ovulation, correct? How many days after unprotected sex would there be a positive pregnancy test or pregnancy symptoms?
I've searched the 'net and I keep getting conflicting info!
