Need opinions!

Brianna • 23. Years old been trying with my husband for 2 years now. Both are excited ro be parents
I am late with my period never have I ever been late in all the years I have been with my man. We have been trying for almost a year and half and no luck. I dont want to psych myself out and get excited when there is nothing to get excited about. I have nausea and my boobs are sore but it could be this time of month. I know the only answer is a pregnancy test but im scared to be let down after trying for so long.
