Advice please

Hi all. I'm what I thought was 9dpo and AF due 30th June. However was getting symptoms yesterday/today. Took a test this am with fmu. Faint line but there. I thought I'd test again this afternoon and this was the result. It's definitely positive. Came up in about 30seconds. Problem is I had a CP last month and my OH and I got really excited at the positive test to them retest the next morning and get a negative followed by AF. Question is do I tell my OH. I did say I wouldn't test until day AF was due. I'm excited and want to share it with him but don't want the disappointment again. Sorry for the essay!
