My last period is July 14 to July 21, I have sex with boyfriend July 24 to August 4 then we fight so I sleep with someone else on only August 7(no condom but did not *** inside me)..... Me and my boyfriend got back together August 10 then last August 28 I have positive pregnancy test, I'm now confused who's the father of my child?  I need some answers pls :(

Get the second ultrasound.  4-5 weeks is too early for precision.  The best time is 6 or 7 weeks.  Not later, though.

Thanks so much for the answer....the doctor says it's more 4-5weeks gestational pregnancy and my symptoms is more like 5weeks pregnancy so it means I concieved the baby on August 7? Coz if 5weeks-2weeks? I wish it's not the August 7 guy coz it's just a mistake not for love.

I think the baby is much more likely to be from your boyfriend, from sex in late July.  Get another ultrasound very soon if you can, and ask your doctor for an estimated due date based on the baby's measurements and developmental markers.  Don't wait, it should be done in your 6th or 7th week counting from the first day of your last period. Once you have the estimated due date, you can use an online calculator to work back to an estimated conception date, or simply count back on a calendar 266 days. Good luck.

And on August 30 I have my transviginal ultrasound and doctor just saw a sac, it read this :
+D2.32cm
10.0cmMI 0.7
Gen TIs 0.4

When do u think I concieved the baby and who's likely more the father?
