Smoking while pregnant

I’m 6 months and 1 day today,

I’m a smoker, only weed and cigarettes but I’m trying hard to go cold turkey today. I’m worried about my baby. Thinking if harm has been done already. I feel guilty but I’m going to stop I promise.

I used to smoke about half a pack a day during the first 3 months

Then I cut down to maybe 3 -5 cigarettes a day during month 4-5 and now I plan to go cold turkey during month 6.

I’m a week in month 6 and I’ve been smoking about 1-2 cigarettes a day. To little puffs here and there.

The doctor dosnt know but is saying my baby is healthy, heart rate and weight. I promise I won’t smoke no more

Is there anything I should be concerned about

There’s a lot I want to say but don’t know how

But basically, am I stopping too late?

I’m scared my baby has birth defects or autism or somthing of that sort.

I’m kinda looking for mothers who also smoked during pregnancy.

I’m really looking for any kind of words honestly, from any one

Please and thank you
