Feel bad

So I'm 24weeks pregnant and I haven't seen a doctor yet... Outside of when I was 7 weeks and then when I went to emergency room and was like 17 weeks....I haven't had any testing or blood work or ultrasounds! I feel like I'm doing this pregnancy wrong with my other 3 I was at every doctor's appointment.....I do feel my lil Prince kicking away everyday.... Which gives me some comfort.... But (, don't judge me) I been smoking cigs cause I been very stressed out....I go back to my hometown where I have my insurance in about 2 weeks....I don't want anything wrong with my baby... I'm just scared and nerves!!! Need to vent and get this off my chest! 😞😢😢💙👣👶
