What to Do? But Wait!

So Ladies, I went to the Drs on Feb 14th, Valentine's day. I took a pregnancy test but it came out Negative. I didnt know what to expect with that, being 1 day before my cycle was to start. Now, It's been 6 days and by the time some would read this, it will be 7 days later, from the 14th. Ladies, I STILL DON'T HAVE A PERIOD!!!! GLOW says I'm 4 days but I'm 5 days late. I want to take another test but I'm kinda scared to. I've been having some cramps, very emotional, MOODY and just feeling weird. I can't sleep, eat but when I get hungry, It's a dying hunger. Like if I don't eat RIGHT when I get hungry, I'll get sick. Most of the time, I don't have an appetite and I'm always in my bed, fatigued. I want to say that I AM PREGNANT but I don't wanna get disappointed. Ladies, Wat should I Do? Besides Wait! This would be my Rainbow Baby🤰
