When Should I Do A Pregnancy Test?

by Shubha
(India, Karnataka)

My last mensuration took place in Feb 9th. So if I am pregnant, which is the exact date that I will come to know that I have conceived.


During my first pregnancy my doctor confirmed it just 1 month 4days after my last menstrual period. Some says that it takes at least one month and 15days to detect the pregnancy after the last menstrual period. Can you guide me?

Answer:

Hi Shubha,

The best time to take a home pregnancy test is the day after your missed period.

Not all women have a positive pregnancy test right the first time, and may need to wait 48 hours before repeating the test.

The home pregnancy test measures the levels of your pregnancy hormone hCG in your urine. The concentration of this hormone doubles approximately every 48 hours.

If you have been tracking your basal body temperature and know when you have conceived you can do a home pregnancy test 18 days after your ovulation day (if you have 18 consecutive high temperature). This is aproximatelly 15 days after ovulation plus a couple of days just to make sure the levels of pregnancy hormone are high enough to be measured.

Your doctor can recommend a blood test if necessary, which will be able to confirm pregnancy earlier.

You need to wait at least 15 days from your ovulation day before testing. This is because 14-15 days is the average luteal phase or a normal cycle. During this time the embryo implants itself in the lining of th euterus.

If you don’t know when you ovulated, by calculating your fertile days you can find out aproximately when your ovulation day was.

If your last menstrual period was Feb 09 and your average period is 28 days long with a 14 day luteal phase you can be 3 weeks and 4 days pregnant. A pregnancy test may or may not be able to give a positive result at this time, wait 4 more days before doing a test to be sure.


Many Blessings!
