How to calculate age of fetus after positive pregnancy test? – Dr. Teena S Thomas
After getting positive pregnancy test the age of the foetus is usually calculated by determining the first day of the last period date, so the calculation start from the first day of the last period date in the number of week, usually the pregnancy last for 40 weeks. So from the last period we calculate the age of the features but this gets accurate only when the person is having a regular period, when the periods are irregular be there is less significance to the last period date, the first day of the last period usually is not very significant because the egg is released two weeks before you miss your period. So we add on two weeks to that, so if a person is having regular period that is every 28 days cycle then usually egg is released in 14 day, so 14 day behind and 14 day ahead. So that counts to 4 weeks. But the period of women is around 45 days the egg is released usually 31st day, so we don't have to calculate the first 31 days before that, so it will be the 31st day from there are two weeks more. So than the calculation varies. So for a normally regular cycle women the calculation is started from the first day of the last period and then all these days can be corroborated and we do an early pregnancy scan, usually the early pregnancy scan is a dating scan. So we can get an accurate reading by going through the first day of the last period date and the early pregnancy scan.
What hapens if you cant rememeber when your last period is
my last period day 22 January n now I test 23 February n result is little bit light then other line.bt I clearly see this line tell me how many weeks I’m pregnant n should I go to the dr for hcg blood test?
Question.. Please do help me and have time to read this.
I had a ONE NIGHT STAND with a girl, it happened on NOVEMBER 15, 2016 then one month after our intercourse, she told me that she’s pregnant and i’m the father according to her, then i couldn’t believe it, because she’s not my girlfriend and we haven’t chatting after we met on the said date. On her period of pregnancy, I supported her. Paid her check up bills and also the medicines. But we’re seldom seeing each other because she’s far away from my place and i’m too busy with my job so I also haven’t been on her check up and ultrasound. Then on JULY 30, she finally delivered her baby. The doctor said to me that the baby was already 9 MONTHS old on JULY 23, 2017. Then I was shocked, because based on my understanding, the baby will be delivered after 9 months of our intercourse. Now i have a doubt that I may not be the real father of the baby and I can’t even ask her about it because she might be upset and offended. After watching your video, i have a little hope that I may still be the father of the baby. Now, please do answer me,
IS IT POSSIBLE THAT I AM THE FATHER OF THE BABY?
Please do have time to calculate it is a big help for me.
