First Response Digital Ovulation kit

Hey guys! We are TTC for the first time this month. I used the above brand for OPK. I got a Yes on day 16 so I Bd 3
​times that day and two times the day after. I was not able to have sex the next day. Do you think that was sufficient for a good chance to conceive? Has anyone else had luck with this brand of test? I'm only on CD20 now so I'm in the dreaded 2ww.  Any thoughts or success stories would be appreciated! -Les
