My cycle is normally 30 days, but last month it was 32 days.i got my last period on july 23rd. from the cycle, how can icalculate my luteal phase? when would my ovulation be on?

Ovulation kit: Since ovulation day change slightly every month if you are trying to conceive and have intercourse during the most fertile days of the month then the use of ovulation kits can be very helpful. You can purchase the kit over the counter. When the lit turns positive the same day and the following day are the most fertile days of the month.

Cycle: The luteal phase starts after the ovulation. If your ovulation falls roughly in the middle of your cycle, then the rest of the days would be the luteal phase.
