Test now or Test later

So today a friend of mine stopped by and as I walked to the car she asked me was I pregnant. A neighborhood of mine was also outside and said he wanted to ask me the day before but didn't want to come off rude. When I told them both I wasn't as far as I knew my friend really thought I was lying and demanded to see my baby bump?!!! So I came back in the house and asked my 2 brothers and husband and they all admitted they saw a slight baby bump and my stomach is firm. Now my period isn't due for another 6 days idk what to do should I try to test today or should I wait??
