Hello,

Thanks for posting your query. I have gone through your history in detail.

According to your Ultrasound report,Last Menstrual Period (LMP) date was 24th November as per calculation from expected date of delivery (31st August). Here I can comment that LMP measured by Ultrasound is one week advance than original LMP (17th-18th November) as you told above.

Actually pregnancy depends on timing of ovulation and unprotected sex. Ovulation occurs approximately 14 days before next due date of period in regular cycle.
After ovulation ovum can survive up to 24-36 hrs, and after ejaculation sperm can survive 3-5 days inside vagina or uterine cavity. So I clarify the situations according to two different LMP with regular cycle.

1) If LMP was 24th November,then possibility of next due date was around 22nd-24th December. In such case, ovulation occurred around 8th-10th November that is fertile period. As you were involved in unprotected sex at that time, then highest possibility of being father is 2nd guy.

2) In case of original LMP 17th-18th November, the next due date was around 16th-18th December. Herein,ovulation occurred around 2nd to 4th December. At that time,you were also involved in unprotected sex. So here chance of being father is the First guy.

It is best and widely advised to undergo DNA test for confirmation of Paternity and to clear doubt or dilemma from your mind. You have to be sure 100% by DNA test only and nothing is superior to that. Please consult with your doctor regarding this and take proper guideline.

In the mean time, do the following basic things:
-Take healthy protein XXXXXXX diet & Periodic check up.
-Continue Folic acid & vitamin supplements
-Avoid stress/tension by regular XXXXXXX breathing
-Adequate rest with left lateral position 8-10 hrs daily.
-Maintain personal hygiene and take breast care.
-Enjoy your pregnancy ahead of anything.

Hope I have answered your query. If you have any further questions I will be happy to help.

Wish you better health and successful motherhood.

Thanks for follow up query.

If your periods come around 30-32 days,then following things can have happened.

1)In case of LMP on 24th November,ovulation occurred around 10th-12th December in next cycle as per calculation. Herein chance of being father is always 2nd Guy and does not alter as compared to previous state.

2)In case of original LMP as on 17th-18th November, ovulation occurred around 4th-6th December in next cycle. As sperm can survive up to 3-5 days after ejaculation within female genital tract. Then having sex on 2nd December, possibility of being father of the first guy also does not alter.

DNA test is superior to over all and surest test for paternity.

Hello,
Thanks for writing back.
An ultrasound is not very reliable in this type of situation when you are involved in unprotected sexual intercourse with two different guys around ovulation time or fertile period. It gives gross & detailed view on the basis of fetal maturity at that time. Development of embryo or fetus may be small for date.

For example, you are calculating period of gestation from actual date of LMP and it is about 6 week plus but when you undergo ultrasound scan, you may get different result (5 or 6 weeks) according to fetal maturity which may not always correspond with actual gestational age. Here maturity of fetus is lagging behind the period of gestation.

Therefore you do simply a DNA test for 100% confirmation of Paternity and to clear all doubts.
I hope I have cleared your confusion. If you do not have any clarifications, you can close the discussion and rate the answer.
