Hi,
Rarely ovulation can occur late. So wait and repeat pregnancytest after one week.
Don't get stressed. Of women trying to conceive 80% of them get pregnant in one year and this is normal.
The very fact that you are having regular cycles means that you are ovulating regularly.
You have not written to me about your age, BMI, duration of marriage and whether you have done any investigations before.
If your age is less than 30 years you can keep trying for pregnancy for another six months.
If you are more than 30 years age consult gynecologist for basic
infertility work up and to be treated accordingly. Hormone teats and
fallopian tube patency test for you and
semen analysis for your husband.
Take one tablet of
folic acid daily.
To increase your chances of pregnancy maintain normal BMI, quit
smoking ( if you both are smokers) and have intercourse at least three times in a week.
I hope I have answered to your satisfaction. If you have any further queries contact me through Healthcare magic.
