Am I too big???

The last 2 years since I graduated high school I gained a lot of weight and the last big chunk of weight I gained very quickly in the last few months, in high school I was a size 3-5 depending on the store and around 115-120 pounds (I'm 5'6") but now I wear size 10-12 and even then pants in that size can be pretty snug and I have to go up a few sizes especially at places like Walmart and target and I weigh around 186 pounds. My husband always says I look just as good as I did when we were in high school but I always assume he says that because he loves me and doesn't want to upset me by saying Iv gotten bigger / less attractive. So do you guys think I'm unattractive??? Here are some photos of before and after my weight gain
