How To Determine The Paternity Of The Fetus?

First man - Highest chance of being father.
Detailed Answer:
Hello,
Thanks for writing to us. Followings are my comments:
1) If your period is quite REGULAR (28-30 days), then your fertile days would be from 29th XXXXXXX to 4th Feb if your D1 of cycle was 18th XXXXXXX Chance of pregnancy from FIRST man is HIGHEST (more than 99%).
2) Unprotected sex with pulled out method has quite HIGH failure rate (15 to 27%) and there is SLIGHT chance (less than 1%) of getting pregnant from 5th Feb sex (by SECOND man) as it was close to your fertile days. However, it needs to confirm.
3) Best thing, you can do, is DNA test to clear doubt and it is superior to all other tests. It is 100% reliable and confirm paternity.
Hope I have answered your query. If you have any further questions, I will be happy to help.
Good luck and all the best.
