Hi, my last period was on June 10th, I'm normally 28 day cycle so I was due my next period on the 8th of July... 4days late now... 3 negative pregnancy tests ! I also know the exact date of being sexually active - 27th June. Is it possible to be pregnant after ovulation? I've had all the usual pms... bad mood, slight cramps a week ago-normally a lot stronger though.. and indigestion... which I never get.

No, you can't get pregnant after ovulation... but you may have ovulated later than you normally do. Give it a bit more time and see if your period just isn't late this month. Try another test in about a week if still no period.
