Is it normal to gain almost TEN pounds in one month pregnant with twins? 🫢 Asking for a friend (who’s actually me). I’m almost 18 weeks pregnant. I have already gained almost 20 pounds this pregnancy. Is this normal for twins? Someone help me who knows what is. My other pregnancies were singletons. I wasn’t underweight but normal, healthy BMI. Started about 126 up to 144 ish now.
