Vaping in pregnancy!

Please do not comment anything horrible :

I have been a smoker since I was 16 and I am now 27. I am 18 weeks pregnant and have been smoking up untill this last week.

I have been replacing cigarettes with a vape. I have been told it's safer using a vape then smoking fags.

However, I want to give up the vape but I'm not quite there yet! I have a addictive personality and wondering if there's anything else I can use!

I mean, is a nicotine free vape a better solution or is there anything else!! This is a big step for me and i don't want abuse thrown at me. There's worse mums out there!

Any advice would help x
