Ttc for 7 months

My husband and i have been ttc #1 for 7 months and so far no luck (he's 32 and I'm 23), I'm currently 13 dpo and haven't got a bfp yet my period is supposed to come in 2-3 days , I keep thinking I'm having symptoms like slight cramping on my right side, cravings(chinese especially)and Nausea. But I'm so worried that it's never gonna happen for us, and if it doesn't happen this month then I'm gonna talk to my doctor .
