Same issue here. Consensual sex, but held down and impregnated without my consent. He knew what he was doing and did not ask me or even consider me obviously. He assumed I could take the morning after pill that would fix everything (however high doses of hormones and I'm nursing our daughter?) and this time he even said immediately after "I think I got you pregnant, do you feel our little son swimming around in there?". It was his birthday and he's been more & more abusive the past year since he got me pregnant the first time, (again not asking) and since our daughter was born, now 9 months old. I think he thought I would leave him because of the abuse and having another baby might make me stay? At the same time he hardly works and wasn't treating me right. Now I'm pregnant and taking care of our daughter alone and there's an order of protection against him, but I haven't brought any charges and wouldn't know what it is even called. We had consensual sex but I never agreed it was okay to stay inside me and get me pregnant!!!! Twice! He lacks self control & is overindulged and spoiled. He's living for free with his mom now, literally only pays for gasoline and $80 a month for the baby. Sees her 6 hours a week, supervised, since he threatened us, the catalyst of me finally leaving. So this is a sign off deeper issues in my opinion. You should never have to trick someone into having a baby with you or try to get them to stay in a relationship. You're creating a life that you are more responsible for. It brings more stress into a relationship if anything.
Wrongful conception seems the closest answer so far.
