feeling negative 😞

Grace
Had my 5 day transfer on the 14th December shortly after and the next day I have cramps but I haven't felt anything since really I have sore boobs but getting confused with what's what after all the side effects to the meds are similar! 
Did you feel anything early and I was very stupid and tested obviously it was negative now I feel so negative as if it's not worked I'm fearing the heart break again 😩Â
