Please please doctors help me out with one thing. My doctor asked me to take letrozole starting on day 3 to day 7. Then to be physically active from day 12 - 18. As per my dates, my day 12 was on 19 january. We had sex on 19 night after 12’o clock midnight. Will that be counted as day 13 instead of 12 or it was the day 12? I got the ovulation white mucus on the very next day, we also got intimated on that night too that's yesterday. Is that okay?
