On 14th day, your follicle size was pretty fine.
Your endometrial thickness is normal also.
Normally, after the ovulation trigger ( injection is given ), ovulation occurs within 36 hours.
After the trigger, it is best to remain sexually active daily for atleast 5 - 6 days to maximize your chances of conception.
Also, an oocyte
survives for 12 - 24 hours only, but the timing of rupture might vary, so I am suggesting a longer period for you to be on the safer side.
