New to the game!

I love reading all of your inspiring post! My husband and I just started trying last month and I’m not to sure what to expect! I have taken 2 tests both negative but I am 6 days late. Thinking I’m in my head and my period could be late due to stress? Who knows! Should I maybe wait a little longer and try a certain test brand? I’ve taken 2 clear blue tests. If anyone has some advice I would greatly appreciate your time and feedback! Thanks ladies!
