Who is the father

[dea09221005]

I had sex with guy A while on a break on Dec 23. My ovulation window was Dec 16-21 with Dec 19 being my highest chance. I got my period Jan 3-8. It was a regular period that I track and I’m on a 25 day cycle. I had sex with my boyfriend Jan 12. My due date is Oct 10! I had an early ultrasound at 8wks and everything matched. but I had him Oct 5. So I wanted to make sure there’s no way it’s guy A

If you had a regular period after the sex with guy A, he won't be the father. Your due date and your baby's actual birth date also don't point to the sex on December 23.

If you aren't married to the dad, for legal reasons (to protect your baby's rights), you should get a DNA test done. Call the clerk in the family courts in your area of jurisdiction and see if they have a list of labs approved for legally determining paternity, and go with the dad and the baby, and all three of you get swabbed. With you witnessing the dad doing his and everyone handing the swabs in, you will know it was handled properly (i.e., that he didn't ask a buddy to go in for him). If the clerk of the court isn't helpful, call your doctor for information on how to set it up, but again, make sure it's the kind of test that's legally admissible to prove paternity in court. (No random drugstore tests.) You don't need this to "make sure it's not guy A," since the dates and your period show that already. But you do need it if the dad is not your husband, since in the future if the child needs support, it will then be in the records already that he is in fact the dad.

Thank you! I know I read that your period could be confused as implantation bleeding so I was jus checking

"Implantation bleeding" is an Internet myth that women worried about paternity repeat to each other like in a game of Gossip. An embryo is smaller than the dot on the letter i in this sentence, and the uterine lining is ready and waiting for it. There might (but probably won't) be one tiny wisp of blood the moment it implants. It will not create floods of blood for days.
