AF late 2 days;BFN

My sisters keep telling me that im causing myself to have pregnancy symptoms because that's all I that I ever think about. I've been TTC for 2 years and now it's day2 that I was suppose to have my period and I still keep getting BFN. Today I was having flutters in my stomach and it was sooo weird, my husband said I'm being dramatic because I always joke around and say I'm going to be over the top when I find out. But seriously I felt something really weird and last time i felt anything like I felt today I was pregnant with my daughter 7 years ago. 

Should I stop worrying and wait it out? Idk I'm so nervous and excited. I just don't want AF to just roll around because It would probably break my heart. 😢🌀😰

I need help! Y'all got all the answers lol
