Brief Answer:
pregnancy starts around 14 +/- 2 days of last period

Detailed Answer:
Hello Dear,

Sorry for delayed response. I am not able to get your query clearly.

Answer of 'Sir what is date pregnancy start after period ' is mentioned below.
Pregnancy occurs when sperm meets ovum in uterus. Ovulation from ovary occurs roughly around 14th day of menstrual cycle (when menses begins count it 1st day). Pregnancy can occur in +/- 2 days of ovulation.
Your last menstruation began on 11th April 2015. Your ovulation was likely around 25th April. So you became pregnant between 23rd to 27th April.

What do you want to ask by saying "as I have intimate 04 may but my last period is 11 Apr so pregnancy date is 11 Apr otherwise 11 may"

Please let me know more information so I can provide you still more clear answer.

- What is your age?

- What are the dates of your last 3 menstrual periods?

- When did you have successful intercourse between 21st April to 5th May ?

- When did you come to know that you are pregnant?

Hope to hear from you soon.

Brief Answer:
rare possibility that you became pregnant on 5th May

Detailed Answer:
Hello,

Thanks for information.

Your cycle duration is 28 to 30 days. Considering your last menstrual period on 11th April your ovulation has likely occurred between 24th to 29th April maximum. Ovum remains viable for fertilization and pregnancy up to 24 hours. It means you became pregnant maximum before 30th April. So technically it is not possible that you became pregnant after 5th May.

You became aware about pregnancy on 15th May. Urine pregnancy test comes positive earliest after 14 days of pregnancy in general and blood test can confirm pregnancy earliest after 9 days. If you came to know through urine test then again possibility is that you did not become pregnant with intercourse on 5th may.

For clarification of this issue hormonal investigation sequentially and ultrasound can help.

Sperms remain viable in uterus up to 5 days. In case there is no intercourse between 21st to 30th April rarest possibility is that there is delay in ovulation.

Understand above facts and discuss with your gynecologist that why such mismatch is there.

Feel free to ask further.

Take care.
