Twin weight gain

Hi ladies. I’m sort of having a hard time with this weight gain and being pregnant with twins. I lost around 8 lbs first 9 weeks, by 14 weeks I was up only 1 lb, and was told that I’m not gaining enough. Since then I just kind of ate whatever I could out of frustration and (I’m 17 weeks) I have gained about4-5 lbs. I WANT to gain enough weight in a healthy way for my babies - but feel like it’s showing up in my face already. I know I’m going to hear don’t worry about the number! BUt just feel like I needed to let it out because I felt like I went from one extreme to the other. Any others with this experience?
