Would you tell your SO you had a pregnancy scare?

So I'm on an ultra low dose birth control pill and one of the side effects is occasionally missing a period. Well I missed mine this month and it freaked me out a bit. I wasn't too worried because I take my pill religiously and we use condoms 98% of the time. But I was worried so I decided to test. It came back negative like I thought it would. But I'm not sure if I should tell my boyfriend about it. I don't want to worry him but I feel like he deserves to know. What do you think?
