Frustrated but proud of myself (ex smoker)

So me and my partner decided just on Monday that we should ttc. I normally am a smoker (have been since I was 18 but not a heavy one) so I’ve quit smoking whilst ttc as want a healthy egg/baby. I’ve tried quitting in the past and it never worked for me. It’s been 5 days and I’m feeling frustrated and anxious but I’m also feeling proud of myself. Temptation has been there but having a baby is more important to me 😊 who else is or has been in my position?
