HI. So I recently found out I am 2+1 weeks pregnant. I slept with my sons dad on the Saturday when we was both drunk after seeing each other on a night out. (split up for 3 years now) and slept with another man the day after ( the Sunday ) who ive been dating for a couple of months now but not serious with. I’m on the pill but due to drinking alcohol I was sick all Sunday. I haven’t told either of them yet that they are a potential father. Because my ex will deny the baby been his and cause a big scene. So My question Is can I get a paternity test while pregnant? Using my sons dna to see if the baby’s his dads also. Would it show as full sibling ? And half if it isn’t? I’m scared and already asingle mother I want to keep the baby 100 percent but I want to find out who the father also. Thanks
