can you develop an eating disorder during pregnancy? will it go away afterwards?

[british and proud!!!]

im 40weeks pregnant and i dont like putting on weight so i eat loads of food in one go and loads of junk food. i then make myself sick afterwards. i do this daily and have been since i was about 3,months pregnant. i only have put on 20pounds in this pregnancy. i put on 50-60 with my first baby. i want to be thin straight after the baby is out so i think ill keep doing this. is this pregnancy hormones that made me like this or something else?

Being pregnant has actually helped me over come eating disorders. I figure my body is not my own, so I eat and eat for my little baby.
I don't know how much the average person is supposed to eat, all I know is that when I am not pregnant I hardly eat at all - I'm not hungry. So during pregnancy I over compensate because I want a healthy child - that is way more important than "my body". I will lose the weight afterward, it's not hard. But if my child is born ill because of something I have done, I would never forgive myself.

I don't think it's hormones, I think it's deeper than that and you should talk to someone about it.
