nervous

me and my fiance have been ttc

for a year now and nothing happened... now this my first time using Glow and I kinda like it; so according to here AF should've been here yesterday and she still isn't here. I've been feeling a little funny like idk if that's my organs moving or what lol but it is a funny feeling plus cramps and heart burn along with the sore breast , and to top it off out of nowhere I get this nervous feeling like heart racing and idk y... I'm want to take a test but I'm tired of being disappointed ..should I follow my gut feeling and take it or just want til tomorrow??

thank you in advance
