TTC at 26 ....

So I was on birth control for nearly 8 years I came off a year ago and been having unprotected Sex since then for the last 3 months actively 'trying' and I don't know I just feel different this month but I swear to god if I come on in the next few days I may breakdown is this normal?? At the moment I'm getting cramps breaking out itchy boobs tired and even sweet smelling urine ... But goodness I'm getting stressed!! HELP
