Hi
Dr. Purushottam welcomes you to HCM virtual clinic!
Thanks for consulting at my virtual clinic. I have carefully gone through your case, and I think I have understood your concern. I will try to address your medical concerns and would suggest you the best of the available treatment options.
1] From your USG it appears that you had last menstrual period on 4 th of October.
2] In a woman with regular cycles, day 10 to 20 of the cycle is the most fertile period of the cycle.
3] In your case it falls between 13 to 23 of October. You must have conceived in that period only.
4] if you happen to have had sex with multiple partners in that period then it is difficult to comment about paternity. If needed you can get DNA paternity test once baby is born, to ascertain father of the baby.
I hope my answer helps you.
Thanks.
Wish you great health.
Dr Purushottam
