Bulimia in pregnancy

Has anyone suffered from bulimia during pregnancy? How did it go? is the child ok? did you go into preterm labor? and when did it start (before pregnancy, early, late)? Please tell me your story. i am currently struggling a lot with my weight gain, and has been purging a lot, and it scares me for my child. It Started around when I entered the 3. Trimester maybe a little before, and I am currently 33 weeks pregnant. Thank you so much for any reply. I am trying my best to stop, and any tips is also very appreciated ❤ please be Kind, i hate myself for this and I dont Know where else to turn. I am overweight, Even before pregnancy.
