Confusion over ovulation

[girlanonymous]

Me and my partner had intercourse yesterday on 7/7. Last period started on the 21/6 and lasted until 26/6. I'm fairly regular as cycles are usually 28 days.

Is there any chance we could have conceived?

If you aren't using contraceptive then yes, of course. On a 298bm day cycle with ovulation in day 14 then you'd have obviate on Friday, but I have a28 day cycle and often ovulate on cd16 which would put you on 7th. If you aren't wanting a baby I'd get the morning after pill
