help please - which day?

[JJKCB]

hello, first time OPK (as I use to get bloods at the doctors) and looking for some advice

a bit of background I had a HSG on monday (cd13) at 10am, that night we had sex at midnight and then at 4am on the tuesday (cd14) but havnt managed to have sex since due to other commitments...

which day do you think I O'd on out of 13 and 14?
and
do you think I may have caught it?

I think CD 14 is when you O'd. Sounds like your timing was pretty good, FX for you!

You normally get a positive opk 12-36 hrs before you ovulate so I would say you ovulated cd14 or cd15? I'm not an opk pro though so that's just going by what I've been told! Good luck!!
