Hey Lauren, How stressful for you! Sending lots of hugs your way.
I am only pg with my first, so I don't have experience as a parent, but I do know that if having a termination is not what you want to do, you should never be forced into it! Perhaps you could try to talk to a councilor at a family planning clinic or something? They can advise you as to what support you could get if you went ahead and had your twins.
I really hope you can find the support that you need right now though. Take care of yourself. xx
