Hello, welcome to HCM, I am Dr. Das
Firstly, in general condition, ovulation occurs around 14 th day of menstrual cycle counting the first day of bleeding, as day one.
In your case, you have to try for pregnancy
10 to 18 th day.
But, these are not confirmed method. The most sensitive test is ultrasound
scan of abdomen.
so, consult with an infertility
specialist for ordering ultrasound monitoring of ovulation. According to this test you have to try for pregnancy.
Best of luck.
