It happened! Should I wait to tell hubby?

YOU GUYS I’m 3 days before AF is supposed to show and I told myself I wasn’t going to test early this month because I always get disappointed. I had an urge to test and used one of my cheap Amazon HCG tests. I couldn’t believe my eyes!!! My husband is already asleep, I drove to Walgreens and got a digital and FR and BAM! I’m still in awe of this. I want to tell my husband tomorrow but I don’t want to tell him if this is too early and there’s a chance for a chemical. Can anybody give me advice? Do I keep testing to make sure the line gets darker? I’ve done so much looking in this group about TRYING but not about what to do when it happens!!!
