Huge weight gain

Dear ladies, I’m 17 weeks pregnant today and I have gained 9kg! I am eating really healthily, normal portion sizes, no junk and exercising but the kgs just keep piling on and my doctor is giving me a really hard time about it. I’m really worried something is wrong to have gained this much weight (my doctor keeps saying I’m meant only to gain 10kg in whole pregnancy) and that it will hurt the baby. I have two large fibroids (10cm each) but not sure if this has anything to do with it! Has anybody else experienced this and have any tips to share? Were you able to do anything about it to get it under control? I’m really dreading seeing my doctor next week 😳 thanks in advance
