Chances of getting pregnant are more when intercourse occurs around ovulation time, i.e., around the 14th day of the cycle. It looks as though you had an intercourse during the fertile period, so it is better if you exclude pregnancy
. The white discharge observed during pregnancy is profuse and watery. A sticky copious discharge is perhaps due to excessive estrogen
and also due to some vaginosis. I advice you to see your gynecologist for an examination and treatment. Take care.
