Please help?! Need advice what does this sound like???

Ok so me and my husband have been ttc for about a year now but took it serious about 7 months ago and I was really hoping this month would be our month but then today I had period like cramps as in that gross feeling whole stomach cramping and it stopped now but it's just weird cause I'm not suppose to start for another 9 days. Does that sound like once again it didn't work and I will get my period? :( has anyone felt this way?
