I'm Scared to test!

So My period was suppose to come on the 26 of this month. And it didn't! I've never been so regular with my periods being they come every few months to almost a year!  I was out of state and went on a treatment and I'm so scared to test! I don't have any symptoms so I know it's a no for sure! Although I'm trying to keep my hope up After two years of TTC I've kinda lost all hops 😕😭
