I have positive ovulation test and i have sex on the same day. Could i be pregnant?
Patient: If i have a positive ovulation test, and i have sex on the same day and day after, but no sex after then, can i still be pregnant . Doctor: Welcome to Healthcare Magic Good Day By Koparday's formula, calculation of fertile period is as follows Your shortest cycle days minus 18 days=1st day of fertile period.  The longest cycle days minus 10 days= last day of fertile period.  Ex: If your menstrual cycle varies from 26days to 31days cycle, The shortest cycle [26days] minus18days=8th day. The longest cycle [31days] minus 10days=21st day.  Thus, 8th to 21st day of each cycle counting from first day of menstrual period is considered as fertile period.  Period other than this fertile period in a menstrual cycle is considered as SAFE PERIOD.
