Pregnant? Maybe soon?

So I’ve supposed to get my period on the 14 of February and it didn’t come. I’m nervous to test, I’m married and I can’t wait to have a child. But the last couple times I’ve tested it’s been negative. I don’t want to test and be disappointed. But over the day I kinda lost my balance a few times. I’m going to give it a couple days and then take a test... kinda excited for good news... but nervous that it would negative.

How long should I wait to test?
