Am I overreacting?

A while back my husband decided to buy himself a sex toy. Naturally it bothered me because although I'm pregnant, he was still getting sex from me. We had a fight over it and he threw it away. Today I was looking for a lighter to light a candle. Guess what I found? He either dug it out of the trash or bought a new one. I had noticed that the past few weeks he doesn't seem as interested in me sexually. I figured he was either being sweet because he knows I don't always feel well, or he was either grossed out at my body. And I'm more than willing to have sex or do other sexual things. The whole reason I dislike the idea of sex toys is because eventually, that toy is going to feel better to him than I will...especially once I have the baby. I'm very upset seeing as how the hole on the toy is no bigger than a dime! Am I wrong to be upset? :(
