Brief Answer:
Ovulation dates

Detailed Answer:
Hi,

I read your query and I understand your concerns.

Following is my reply:

1) If you had your menstruation on December 27, your ovulation would be around 10th January if you have regular cycles.

2) Hence the father of baby in all probability should be the person you were with in these days as ovulation and fertilization would have occurred these days.

3) The other person with whom you had sex on 22 January cannot be the father as it is way out of ovulation period.

Let me know if you have anymore questions.

Regards,
Dr. Mahesh Koregol
