Pregnancy after Miscarriage

Hey ladies !!! So I recent found out after trying for the past 4 months my fiancé and I are finally pregnant again since our miscarriage in May after taking clomid . I go in Thursday for a blood test and I am terrified .... the last time I went in for a pregnancy appointment I was alll super excited just to see a empty sac on the screen . I am so scared to go to this apt and have them tell me my levels are normal... needing positive vibes and if anyone else has taken clomid if it worked for them and how that pregnancy went for you ???? Any feedback is much much appropriate. Thank you
