He might not come out looking like either parent. You or the biological father. Even if he did it wouldn't matter much. You still will need to determine who the father is. The child has a right to know their father and the father has a right to know if they have a child. When they come of age or even before that they might want to seek them out and that shouldn't be denied to them, even if you choose not to speak to them.
, I dont talk to the father anyway so a DNA test wont be needed i just wanted to ask you girls just to get a better vision of how my son would come out lookinqq !,
There is no way to tell without a paternity test.
first of all it wasn't your period if you were already pregnant, that would have been spotting. and secondly there is no possible way to tell. ultrasounds can be off by up to a few weeks and we can ovulate late. one cycle can be longer than the next, throwing off our ovulation. so many things come into play. you had sex with them far too close together and you will need a DNA test. ask your OBGYN about getting a DNA test via amniocentesis when you are about 16 weeks and if you arent comfortable with doing that because of the risks then you would have to have a DNA test done after the baby was born.
either way you need to be honest with both guys and let them know whats going on.
