1st baby - need your experiences

Hi, I'm now 5w3d.

I don't have much symptoms (only my boobs) but my head is driving me crazy.

Every morning when I wake up I first check if I'm bleeding and throughout the day I check everytime I wipe.

I'm struggling to quit smoking too. I smoked a lot before I found out I was pregnant and I'm only smoking up to 3 light cigarettes since then. I really want to quit but especially in the evening I'm craving..

I don't know how to handle this. :( any advice?
