When to discuss possible pregnancy with your SO...

My husband and I have been ttc now for 4 months. I told myself I was not in a rush and if it happened great and if not, I wouldnt be upset. Last month I felt so off, my body felt strange, all the early symptoms matched and I truly thought I was pregnant. I got way more excited than I expected and told my husband how I was feeling. He was even more excited than me. Turns out, I was wrong, I was not pregnant and felt terrible that I had got his hopes up. I dont think its fair to me to experience and deal with the excitement/anticipation/anxiety alone but I also dont want to go thru seeing him that let down again. Should he not be told until I know for sure?? That doesnt seem fair to him though either. Help! Id love some advice on this.
