Please please!!!!...When did I conceived?

Catherine

Hello ladies, I really need your help on this as I am a bit confused just I need your experience. So my cycle are always irregular, I had sex 4 days before I got the positive smiley face on clear blue ovulation text (which was day 10) that means I ovulate day 11, so I waited and did sex again 4 days after that (on day 14), and to realise 2 weeks after I did conceived.

My question is when exactly did I conceived? On day 11 or day 14? As my cycle this time was really short as was only 24days.

Please please help if anyone knows something about it!!!
