Postpartum weight gain?


I gave birth to my daughter on March 24th. I lost 17 pounds after I had her. Now I have been rapidly gaining weight (24lbs!!!)and I now weigh more than I did with her at the end of my pregnancy 😳😳😳 I have an appointment coming up next week. Is anyone else going through this? I am so miserable I could cry. With my other two children I held onto weight but I definitely did not gain. I'm wondering if it's something wrong with my thyroid?

EDIT: turns out I have really bad hypothyroidism. My numbers were crazy!! Explains everything!
