A or B Help

[Delilah90]

My period was October 1st through the 6th.

On October 6th i had unprotected sex with guy A. He pulled out. I checked myself after we were done and did not smell or feel anu semen and i am taking it into consideration that there could have been pre ***.

From October 8th through the rest of the month i had constant sex with guy B and he came inside me every single time.

According to my period app which every month is always on point when it says i am due to get my period it also tells me when i am fertile and ovulate. So according to it i was fertile from the 10th through the 15th and i was ovulating on the 15th. I was with guy B all these days and he was finishing inside every time. According to all these concieve dates and my lmp it says i conceived on the 15th of october.

Do you most likely think B is the father? I honestly feel 99% he is and 1% a could be but i doubt a is because he pulled out and B has been finishing every time and we were very active. What do you guess?

Guy B is the daddy.

If guy A put any sperm into you from it coming along in the pre-ejaculatory fluid, it could have lived until the 11th or possibly the 12th in your reproductive tract.  If you were certain you ovulated on the 15th, the first guy would be ruled out.  It just depends on whether you might have ovulated on cycle day 11 or thereabouts.  Ask for an ultrasound in your 7th week (counted from the first day of your last period, i.e., now).  Tell them your cycles are too irregular to use to determine how far along you are and you'd like them to tell you the estimated due date based on an ultrasound measurement of the embryo and its developmental markers.  They should be able to get very close to spot-on if you get the ultrasound right away.  If you wait, it will be less accurate for this purpose.

its is most probable it is B's.... cycle day 6 (oct 6) is too early although not impossible to have ovulated.
I wouldn't worry too much once you start having your early doctor appointments they will measure your baby and give you a better conception date which should fall mid cycle.
