If your cycle are regular then ovulation usually occur before 14 days of 1 st day of menstrual period.So for 28 weeks cycle ovulation occurs 28-14=14 for 32-14=16.so chances of getting
pregnant are at most around 72 hours of ovulation.
For more accuracy consult gynecologist and undergo ultrasound ovulation study
